Release Date

2024-01-04

Fixes

Expand to see the full detail of resolved issues here

Database

  • Improved failure recovery for object storage in Storage Manager. This resolves a case where EOI would not complete and would report SM Flushing filesystem with [directory] errors.

  • Resolved a bug in which EOIs were not completing, and NoSuchKey errors were occurring after moving data to object storage.

  • Improvements have been made to the refresh token logic for AWS deployments. Previously, token refresh logic was erroneous if the session was not requesting object storage bucket data. The refresh rotated every 30 minutes instead of at the session expiry time. Session expiry time is configured with EC2 instance metadata, or by KX_KURL_AWS_TOKEN_DURATION when using Amazon STS.

Security

  • Various CVEs have been remediated as part of this release.

1.7.1

Release Date

2023-09-19

Fixes

Expand to see the full detail of resolved issues here

Database

  • Resolved an issue with the Storage Manager not rolling back aborted transactions if an EOD failed.

  • Deleting data from the HDB using a filter option now correctly performs the delete. Previously, this returned an error claiming that the column(s) being filtered didn’t exist.

  • EOIs are no longer delayed after an EOI recovery event. Previously, it was possible for EOIs to become held up if the process was terminated then subsequently recovered. The EOIs would still complete successfully, but with a delay.

Security

  • Resolved CVE-2023-37920 Certifi's removal of e-Tugra root certificate, by upgrading the spaCy dependency.

Stream Processor

  • Attempts to horizontally scale pipelines using the direct write feature will now explicitly error since this is not currently supported.

1.7.0

Release Date

2023-08-25

New Features

kdb Insights Database

  • End-of-day writedown memory controls

    The Storage Manager (SM) process now supports restricting memory consumption for data writedown, giving the opportunity for cost savings. Reducing the RAM allocated to SM may cause EOD to run longer than if RAM was unrestricted.

    For guidance on tuning your RAM setup, see Performance best practices and the recommended system sizes for Azure here.

  • Deleting data from the HDB

    The ability to perform targeted deletion of data from the HDB has been added. This lets you clean up unncessary or incorrect data without having to remove an entire partition where there may be data you need to maintain. There are a variety of ways to specify the data you wish to delete. See Database delete for further details.

  • New Authorization Options

    Authorization capabilities have been extended to enable linking out to other authorization providers or to write your own. You can now set up a sidecar that offers either an HTTP or IPC interface for authorization to the Service Gateway of the database. See Custom HTTP Authorization for more details.

  • Backfill a new column with derived data

    When adding a new column to your schema, you can now define a custom function that will backfill the new column with derived data.

  • Publishing derived data from custom APIs

    Custom APIs that generate derived data can now stream and/or persist their output.

Reliable Transport

  • Flexible subscriptions to data streams

    RT supports the option to control at what point in a data stream you wish to subscribe. This new feature adds the ability for a subscriber(s) to subscribe to new data only. This is useful for subscriber(s) who do not need to receive historical data and just need to begin receiving data from the latest point onward. The API exposes information about what data is available to subscribers. This is available for use when subscribing using the C and q interface.

  • C Subscriber Support in Reliable Transport

    The C language interface for RT is now able to subscribe to the data on an RT stream if the subscriber is inside the cluster. See here for more details. A new subscriber is now able to subscribe from the last message added to the stream as well as from the earliest message the stream holds.

Improvements

kdb Insights Database

  • End-of-day writedown performance improvements

    The Storage Manager (SM) process has been optimized to significantly improve its performance - up to 50-70% reduction in EOD duration. This improved EOD performance can reduce the memory allocated or the time taken for writedown, depending on your workloads and configuration.

    For guidance and best practices on how to configure your schema and system to take advantage of these optimizations, review Performance best practices and the recommended system sizes for Azure here.

Stream Processor

  • Readers

    • When using cloud and file readers, you can now use filename pattern matching to ingest multiple files using a single reader. This expands the ability for you to build up ingest workloads that pull in multiple files. For example, using an S3 reader, you could read all CSV files in all folders within a bucket using the pattern:

      s3://path/to/bucket/**/*.csv
      
    • When using cloud and file readers you can now use a file watcher which is usually paired with filename pattern matching described above. The reader will continually watch for new files matching the file path(s) provided. See here for details on:

      Not to be used with the Write Direct to HDB option

      The Watcher options should not be used when also choosing the Write Direct to HDB option in the Database Writer in the UI, or the q or Python APIs.

Fixes

kdb Insights Database

  • Fixed an issue where schema type conversions from strings to GUIDs would fail and cause a type error.

  • Fixed an issue on certain NFS-based system (namely Lustre) where the ‘current’ database pointer could get converted to a directory resulting in an unexpected error.

EISDIR: /data/idb/current.new -> /data/idb/current
  • An error has been fixed that would occur when updating an object storage tier that used an inventory file after a data migration.

  • Fixed an issue when querying with .kxi.getData using a groupBy operation on a foreign key column where the name of the foreign key column would be thrown and the query would fail to complete.

  • A new warning has been added to the Resource Coordinator if no Aggregators connect to it. After a wait period, if an Aggregator continues not to connect, this will be escalated to an error to indicate that the system is not ready for queries.

  • When the kdb Insights Database was configured with an object storage tier but an inventory file was not provided, the Storage Manager would error on startup with invalid object storage URI error. This has been changed to not attempt to create an inventory file if no configuration is explicitly provided.

  • Resolved an issue when attempting to migrate HDB data to Azure Blob Storage. Previously, this would fail with a signature error.

  • Fixed a potential race condition between NFS replication and DAP reload signals. It was previously possible that a DAP may reload before NFS replicated data which could result in data gaps. A new sequencing mechanism has been added to ensure DAPs do not reload until replication is complete.

  • Values in a symbol column will now be properly available immediately after a batch ingest. Previously, these would be missing until the next EOI.

  • Renaming a sort column no longer errors.

Fixes

Database

  • Fixed an issue where renaming columns in the schema UI would incorrectly delete the underlying column and create a new one with null data. Column renames in the UI now correctly preserve the column’s data.

  • Fixed a potential race condition between NFS replication and DAP reload signals. It was previously possible that a DAP may reload before NFS replicated data, which could result in data gaps. A new sequencing mechanism has been added to ensure DAPs do not reload until replication is complete.

  • Fixed an issue where converting a column from a string to a symbol would throw a type error.

  • An error has been fixed that would occur when updating an object storage tier that used an inventory file after a data migration.

  • A new warning has been added to the Resource Coordinator if no Aggregators connect to it. After a wait period, if an Aggregator continues not to connect, this will be escalated to an error to indicate that the system is not ready for queries.

  • REST queries could have input parameters converted to the wrong type when multiple type options were possible. REST APIs were converting to the maximum possible type instead of using the correct default type.

1.6.0

Release Date

2023-06-20

New Features

Database

  • A custom authentication function is available for the kdb Insights Database to restrict user access using role-based access control using a q function. See custom IPC authentication for details.

  • The kdb Insights Database now supports a kdb+ tick interface as well as a new custom bus interface.

Reliable Transport

Reliable Transport now supports a one-node as well as a three-node cluster:

  • In a three-node cluster, RT can offer fault tolerance and high availability (HA).
  • In a one-node cluster, fault tolerance is still present, however it is not highly available. This configuration saves resources and therefore costs for workload use cases that do not need to be highly available. If the 1 RT node were to go down, the publisher would continue writing to its local RT log file. Once the RT node has restarted, it would then retrieve any data that is present on the publisher node that it has not yet received.

See here for more details on the RT architecture.

Improvements

Database

  • The kdb Insights Database now validates that primary keys for a partitioned table include the partition column. Previously, setting a primary key on a partitioned table that was not the partition column would error when queried.

  • Query timeout messages now indicate a reason for the timeout. Previously, query timeouts gave no reason, or said “timed out for unspecified reasons”. See queueing timeouts for more details.

  • Greater stability through the use of Kubernetes discovery between the Service Gateway and database processes.

1.5.3

Release Date

2023-06-09

Improvements

  • Resiliency improvements have been made to ensure the kdb Insights Database can recover from multiple days without end-of-day processing having completed. Previously, if more than 2 EODs were missed, it was possible to get a misaligned error on recovery.

  • The kdb Insights Database can now work with or without an inventory file provided for an object storage tier. Using an inventory file for your object storage tier is still the recommended configuration, as this leverages caching and greatly improves performance when querying object storage data.

Improvements

kdb Insights Database

  • SQL queries that filter by time but do not explicitly select the time column are now supported.

Fixes

Expand to see the full detail of resolved issues here

kdb Insights Database

  • Databases without object storage tiers will no longer error and restart to resume normal operations after a schema conversion is performed.

  • New validation has been added to ensure that the snap value set in the EOD schedule of an assembly is always a time value. Previously, some examples showed usage of this field with a timestamp which was incorrectly ignored.

  • Sidecar containers are no longer automatically registering to object storage IAM service accounts where available. With large deployments, this could result in causing authentication backoffs for more mission critical processes.

  • The kxi_da_request_time metric has been changed to use a histogram type to reduce metric output. This was previously a summary type.

  • A new connection heartbeat has been added from DAPs to RC to improve connection stability when an RC restarts and is scheduled with a new IP.

1.5.0

Release Date

2023-05-09

[NEW] New Features

kdb Insights Database

  • The kdb Insights Database now supports a REST interface for loading historical datasets into an existing database. You can now perform a historical batch ingest using a simple REST API. For more details, see batch ingestion.

  • To protect against reserved word and column name conflicts, the way labels are passed to a query has changed. Labels should now be specified either as a dictionary, or with the prefix label_. The old label style is still supported in 1.5, but is deprecated and will be disabled by default in 1.6. See upgrade considerations on labels for more details.

  • Distinct has been added to the available aggregations in getData for database queries.

Stream Processor

  • The Stream Processor Python API can now leverage automatic schema conversion using a new function kxi.sp.transform.schema.

  • Users can now use the Kafka Schema Registry in Python using kxi.sp.read.from_kafka.

  • String manipulation utilities have been added to the Stream Processor Python and q APIs, allowing users to selectively convert the string data to upper or lowercase representations for the purpose of data cleansing.

  • Pipeline deployments now support pipeline replicas, providing enhanced resilience to deployed pipelines. Users can now choose to run their pipeline with replicas for high availability in the Stream Processor. This replaces the previous use of pipeline groups.

Reliable Transport

  • Reliable Transport now offers subscribers the ability to use dynamic client-side filtering, enabling users to control what parts of the data feed their subscribers need to receive. This can greatly improve ingestion performance by eliminating the need for subscribers to handle discarding of unnecessary data. See Filtering for more information.

  • RT has introduced logHistory, a new API to assist in analysis and debugging. The API returns metadata about the RT log file history for logs that are no longer available. This includes:

    • The log file name.
    • The time of the first message added to that log file.
    • The position of the first message added to that log file. See Log File Meta Data for more information.

Improvements

kdb Insights Database

  • Batch ingest now supports ingesting tables that have no symbols. Additionally, extra validation has been added to verify symbol integrity.

  • Batch ingest now supports sorting of columns.

  • The kdb Insights Database gateway now supports returning responses that are greater than 2GB for IPC requests. See routing configuration for more details.

  • Database schemas in the UI can now be modified for assemblies that have been stopped. See schema modification.

  • Requests that supply a log correlator (logCorr) will now see that correlator in the Service Gateway logs. Previously a random correlator was used in the Service Gateway logs.

Fixes

Expand to see the full detail of resolved issues here

kdb Insights Database

  • Migrating tiers to object storage could fail with the eventual error SMDBM Migration discontinued due to failure if multiple threads were used.

  • New validation has been added to prevent accidentally adding a object storage tier to a database that does not already have one. This would previously error at EOD with a file not found error.

  • Schema conversions are now more robust on network based file systems (ex. Rook Ceph). Previously, this could result in a EXDEV. OS Reports: Invalid cross-device link error in the Storage Manager.

  • Changes to disk sort columns in a schema that would be incompatible with the current disk sort will now error with a clear message at deploy time. Previously, this would error with a u-fail error either at an EOI or EOD.

  • Batch ingest can now gracefully handle scenarios where there is no data provided in the session. Previously, this would result in the following error: Error reporting to licensing server: Value must be a long, leaving the ingest pipeline stuck in a RUNNING state.

  • When removing a symbol column from a table, the SM should be able to properly handle its removal as well as the sym file.

  • If an in-memory sort is applied to a column in a schema, it is now sorted on arrival in the RDB. Previously, if data arrived out of order with this set, an s-fail error would be thrown.

  • In the Storage Manager metrics, the kxi_sm_hdb_date_records metric no longer reports an empty value at startup, which resulted in false alerts about the HDB being offline.

  • The Storage Manager now double buffers its state table in order to protect against corruption.

  • The kxi_sg_pending metric would previously be decremented twice when a connection closed, resulting in negative pending values.

  • The Service Gateways were creating duplicate connections to Resource Coordinators while they were waiting to come online. This was resulting in a large number of redundant connections being opened between the services. In large deployments, this could result in conn errors in the Resource Coordinator.

  • RDBs and HDBs that require a dependency on the IDB will now error at startup if one is not specified as part of the mount configuration.

Stream Processor

  • The presence of a UTF-8 byte-order mark at the beginning of CSV files will now be automatically removed from data when acted on by the Stream Processor CSV decoder.

  • Window nodes in the Stream Processor can now accept dictionaries as input batches. Previously, incoming dictionaries would be merged with input batch in the buffer, instead of appending to a buffered list of dictionaries.

  • The Python write.to_database API previously converted assembly names to booleans. This is now resolved, and also fully supports the direct write functionality.

  • The default onFinish functions for the apply node have been updated to have the correct parameters and examples of flushing a buffer.

  • When using directWrite functionality in .qsp.write.toDatabase, table names as strings are now supported. Previously, this had to be a symbol.

  • Security vulnerabilities patched in the Stream Processor for the following CVEs: CVE-2022-41910, CVE-2022-41902, CVE-2022-41900, CVE-2022-41880.

[FIX]: Migrating tiers to object storage could fail with the eventual error SMDBM Migration discontinued due to failure if multiple threads were used.

[FIX]: If an SM client cannot connect to SM after a number of retries, it will now restart the pod to try to automatically recover. This resolves connection issues in DAPs when there are network connectivity issues.

[FIX]: The Service Gateway was creating duplicate connections to Resource Coordinators while they were waiting to come online. This was resulting in a large number of redundant connections being opened between the services. In large deployments, this could result in connection errors in the Resource Coordinator.

2023-04-04

Fixes

Service Gateway

[FIX]: Fixed remote code injection vulnerability in Snake YAML CVE-2022-1471.

Stream Processor

[FIX]: Stream Processor file reader nodes (Azure, S3, File and Google storage) when attempting to read multiple files would only process the first file presented.

[FIX]: Stream Processor Azure file reader was failing when attempting to read a file with chunking enabled, resulting in limitations on the files that could be read.

[FIX]: Heartbeat logs were previously logged as INFO logs, they are now set to TRACE to reduce log output.

Storage Manager

[FIX]: Requests to object storage (Azure Storage, AWS S3, Google Cloud Storage) will now backoff and retry if they get a throttle request from the vendor. Jitter will be introduced to the retry to ensure that replicated processes do not all retry at the same time.

1.3.5

kdb Insights 1.3.5 release.

Release Date

2023-03-16

Fixes

Storage Manager and Data Access

  • Storage Manager and Data Access processes now retry, with exponential backoff, when object storage authentication fails. Previously, rate limiting of authentication token refreshes on large kdb Insights deployments could cause access failure, and subsequent processing issues. For more detail, see the release notes for Core 4.0.2

1.3.1

kdb Insights Microservices 1.3.1 release.

Release Date

2022-12-06

New Features

Storage Manager

  • SM now supports writing its own inventory file, under the tier settings. Inventory files can speed load times for databases - you can read more here.
      - name: s3
        mount: hb
        store: s3://kxi-sm-test/bucketroot/db
        inventory:
          enabled: true
          location: s3://kxi-sm-test/bucketroot/inventory.tgz

The DA should be configured to set KX_OBJSTR_INVENTORY_FILE as an env var to a path relative to the root of the bucket. For example bucketroot/inventory.tgz.

DA/Aggregator

  • The garbage collection in the DAP and Aggregator processes has been moved to a staggered timer for improved query throughput. The default is 10 minutes, and is configurable through the KXI_GC_FREQ environment variables on each service. Previously, the garbage collection ran after each query.

Fixes

Storage Manager

  • Tables with names starting with underscores are no longer considered invalid.

  • Schema changes no longer fail on assemblies with configured—but empty—object storage tiers.

Data Access

  • An upgrade issue where DAs could register with SM before all tables were ready has been fixed. This could result in Error executing listener for event discovery

1.3.0

kdb Insights Microservices 1.3.0 release.

Release Date

2022-11-22

Storage Manager

[FIX] Multiple issues due to connections not being re-established if they dropped and tty being enabled in some scenarios causing debug prompts.

[FIX] An issue where the storage manager exhausted all available connections when registering DA clients that were repeatedly failing.

Service Gateway

[FIX] A problem where the gateway would not respond to a query if it died during query processing due to an out of memory error. The gateway will now issue timeouts for queries that have exceeded their original timeout by more than 5 seconds.

Metrics

[FIX] An issue where enabling metrics for the .z.ps handler caused the 0 handle to not return results.

1.2.1

kdb Insights Microservices 1.2.1 release.

Release Date

2022-10-20

Storage Manager

[FIX] An upgrade issue affecting migrations from kdb Insights Microservices 1.1 using object storage tiers has been fixed.

[FIX] A problem where underlying system calls could cause Storage Manager to hang during EOI or EOD has been resolved.

[FIX] Discovery issues with DAPs when Storage Manager was used in sm-single mode have been resolved.

[FIX] Storage Manager now retries if it's unable to initially reach the Reliable Transport.

Licensing

[FIX] Airgap licensing problems due to lack of support for regional AWS STS endpoints have been resolved.

Known Issues

  • If you request too much data in a single getData(), the request will fail. To overcome this issue you should request less data per getData() call. The error message returned will look like the example below:
   {"header":{"http":"json","corr":"6dd8f0c5-1895-49c9-a87a-636a834af370","logCorr":"6dd8f0c5-1895-49c9-a87a-636a834af370","client":":10.0.10.76:5050","api":".kxi.getData","protocol":"gw","numRP":1,"ogRcID":"10.0.10.100:5060","to":"2022-04-07T11:41:35.717000000","retryCount":0,"rc":42,"ac":10,"ai":"Agg died"},"payload":[]}
  • .qsp.read.fromDatabase cannot be run in a pipeline to query a kdb Insights database. The following example code can be used as a workaround to query data (ex. reference data to be used within a pipeline).
onResponse:{[hdr;data]
    if[0 <> hdr`ac;
        .sp.log.error ("Query failed host=%s, api=%s, code=%n, error=%s";hdr`gw; hdr`api; hdr`ac; hdr`ai)];
    publish data
    }
.qsp.onStart {
    h:hopen hsym `$"sg-gateway-host:5050";
    res: neg[h] (`.kxi.getData; (enlist `table)!(enlist `instruments); `onResponse; (0#`)!());
    }
.qsp.run .qsp.read.fromCallback[`publish] .qsp.write.toConsole[]
  • If metrics reporting is enabled within a microservice, along with the handler for .z.ps, services calling through the .z.ps with 0(f;x) will throw a type error due to a failure in the handler to return correctly. The workaround, if metrics reporting is enabled, is to disable the .z.ps event handler in the metrics configuration for all microservices.

Upgrade considerations

  • If using a kdb+ tick tickerplant, the schema for database signals has changed to the following, which must be updated in the tick sym.q
(`$"_prtnEnd") set ([] time:"n"$(); sym:`$(); signal:`$(); endTS:"p"$(); opts:())
(`$"_reload") set ([] time:"n"$(); sym:`$(); mount:`$(); params:(); asm:`$())

Upgrade considerations

Licensing

From 1.1.0 licensing changes are included to enable feature and comsumption based licensing in some cases. As part of this Microservices now require clients to upgrade to new licenses with feature flags. Previous licenses only required KXCE in the banner.

To validate if a license has feature flags, start a process or Microservice using it and check .z.l 4 in the terminal. This should return something like "insights.lib.embedq insights.lib.pykx insights.lib.sql insights.app.rt insig..

1.1.2

Release Date

2022-07-15

Changes

Storage Manager & Data Access

[NEW] Late and out-of-order data handling

[NEW] Data received out of order is recorded with an appropriate ingest timestamp

[NEW] Late data is recorded, irrespective of where its correct destination is in the lifecycle (RDB, IDB, HDB)

[NEW] Late data is included by default for all requests, getData and ANSI SQL

[NEW] Late data can be filtered out (for example, to see only data present in the system at a particular point in time)

[NEW] Performance is not significantly impacted by late data arrival

[NEW] Reference data can be queried in the Explore Window, in a data pipeline and as part of the getData() API

[NEW] Support for non time-series reference data in Database

[NEW] Data in reference tables can be joined to time-series tables in free-form q queries or getData Improved SQL support for queries (joins and complex queries, except for reference tables)

[NEW] Compression support, including object storage

[NEW] Improved resiliency and performance

[FIX] The getData API endpoint no longer returns an error when an outputTZ is provided.

[FIX] Queries against the interval tier (idb) around the end-of-day rollover process could return zero results.

[FIX] Reference data joins which do not include the foreign column or where the foreign column has a different name are now possible.

[FIX] An issue where certain queries using count could throw the error Error: noupdate: `.Q `pn has been resolved.

[NEW] Stream Processor now supports arbitrarily nested namespaces to include operators

[NEW] API added to allow extract of metrics and status for Stream Processor pipelines

[NEW] Pipeline recovery from Controller fault. Workers die after configurable timeout rather than right away and workers retry connection to Controller host:port periodically after disconnect

[NEW] Support added for chunked file reading. Chunked reading will leverage a concept called 'partials'. Readers will indicate if they write 'partials' into the stream. This will be identified by a new optional emit partials discovery function in the reader's plugin interface. By default this function will return false. If a reader emits partials, the next operator in the pipeline can indicate it buffers partials. If a plugin can buffer partials the partials will be sent directly to the operator. If it cannot read partials, a buffer operator will automatically be inserted in the pipeline that will buffer all partials until a full message is available. If an operator emits partials, it must implement a combine function that merges partial results. This combiner will be made available to the downstream operator.

Proposed API additions:

generatesPartials - This operator will output partial results emitsPartials - Should partial results be passed downstream if the next operator can handle it? combinePartials - Given n sets of partials, combine the data processesPartials - Indicates an operator can process partial data usePartials - Indicates to the operator that data will be provided as partials

The result will allow readers to emit partial results. If decoders can process partials directly they will be given the partials function and partials when available. If they cannot, data will be buffered until a full message is emitted. This will also allow reduce operations to be distributed with partial results being emitted to a combine stage and being buffered before they are finally emitted.

[NEW] API for retrieving the DAG spec from a running pipeline to manifest in the UI

[NEW] Pipeline teardown API - REST clients such as the UI should be able to request the teardown of a pipeline to the coordinator. Teardown should request a teardown from all workers. After the workers cleanly exit, the controller and worker resources need to be deallocated. This includes removing pods, stateful sets, services, etc.

[NEW] Coordinators now use heartbeats to identify pipelines that are still active

[NEW] Kubernetes workloads to StatefulSets, for future integration with RT as well as better persistence of checkpointing

[NEW] Kafka reader 'fromBeginning' / 'fromEnd' usability added

[NEW] Length error running passing some atoms to a pipeline

.qsp.run
    .qsp.read.fromCallback[`publish; `publish]
    .qsp.map[`myMap; {x+1}]
    .qsp.write.toConsole[]

If you pass this pipeline the atom 1, it works fine

publish 1 But if you call it on something with more than one character, you get a length error in .spwrite.console.write

publish 100 I'm not sure what the error is here. Can pipelines accept atoms, or is the issue that .sp.console.write isn't handling them? If pipelines can't accept atoms, it should error earlier

[NEW] Stream Processor now includes CSV Decoder - operators and basic type casting

[FIX] .sp.push isn't working for operators with foreign values as parameters

[FIX] Kafka commit offset on checkpoint

[FIX] Kafka library was not reading from the start of a partition

[FIX] .qsp.run was not starting all parent pipelines

[FIX] Added cleanup callback on pipeline teardown

[FIX] .qsp.filter should verify the type of the return value

[FIX] Runtime fails to compile when operations have the same ID

[FIX] isAsync dict is was incorrectly formed if two plugins had the same ID
