Known Issues

KXI Sidecar

• Users should disable kurl auto register within the kxi-sidecar container. Multiple registrations from component and sidecar could cause throttling.

Setting the below environment variable within the container spec will disable the auto register.

```yaml env: - name: KX_KURL_DISABLE_AUTO_REGISTER value: "1"

1.4.3

kdb Insights Microservices 1.4.3 release.

Release Date

2023-04-20

New Features

kdb Insights Database

[IMPROVEMENT]: 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.

Fixes

Stream Processor

[FIX]: Security vulnerabilities patched in the Stream Processor for the following CVEs: CVE-2022-41910, CVE-2022-41902, CVE-2022-41900, CVE-2022-41880

kdb Insights Database

[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.

1.4.2

kdb Insights Microservices 1.4.2 release.

Release Date

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

1.3.3

kdb Insights 1.3.3 release.

Release Date

2023-03-01

Fixes

Storage Manager

• A limitation to the number of objects that could be present in an object storage tier has been fixed. This could cause EOD data migration to object storage tiers to fail in SM version 1.3.6.

1.3.2

kdb Insights 1.3.2 release.

Release Date

2023-02-21

Fixes

Storage Manager

• Object storage copy limits (2GB) no longer block SM from migrating large columns to an object storage tier.

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.

[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

Service GatewayStream ProcessorMetrics

• 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.

"metrics": {
    "enabled": "true",
    "frequency": 5,

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:`$(); params:(); asm:`$())

• .qsp.read.fromDatabase cannot be run in a pipeline to query an Insights database. The following example code can be used as a workaround to query data (ex. reference data to be used within a pipeline).

    .sp.log.error ("Query failed host=%s, api=%s, code=%n, error=%s";hdr`gw; hdr`api; hdr`ac; hdr`ai)];

• 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

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..

Database (Service Gateway, Data Access, Storage Manager)

• Critical invalid configuration will now fatally exit the process with a FATAL log message and information on the configuration error
• Assembly mounts.*.uri is now defined as mounts.*.baseURI - existing assembly files will need to be updated accordingly
• Update to RT Client Library for new API signatures: https://code.kx.com/insights/1.1/microservices/storage-manager/sm-interface.html#interface-with-a-messaging-service

[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
