KDB.AI q API
This page contains the references for KDB.AI's q API. For example usage, see the Quickstart Guide.
Introduction
KDB.AI q API allows KDB.AI Server users to achieve the following:
- Load and use existing kdb+ datasets in KDB.AI.
- Apply KDB.AI functionalities to external kdb+ datasets.
KDB.AI is a high-performance vector database designed to manage real-time, unstructured data and power AI applications with advanced search, recommendation, and personalization features.
Kdb+ is a high-performance time-series database widely used in industries like finance for managing large datasets, particularly time-sensitive data. It is built to handle vast amounts of structured data efficiently. The q programming language is an integral part of kdb+ as its query language, designed for working with complex, high-speed analytics on large datasets. Q provides a concise syntax and is optimized for the operations typical in kdb+, such as querying and manipulating time-series data.
Pre-requisites
Before you start, make sure you have the following:
- Access to KDB.AI Server.
- Knowledge of writing q code using an environment of choice (command line, IDE, notebooks).
Version
getVersion
Retrieve version info from server and compatible client min/max version.
Example
gw(`getVersion;`)
Error handling:
Description | Message | Troubleshooting |
---|---|---|
Success. version info is returned. | serverVersion clientMinVersion`clientMaxVersion!("1.4.0";"1.4.0";"latest") |
N/A |
Error: KDBAI is not available. | Cannot write to handle ... | Check your connection and if your server is running. |
Database
Create, delete, and retrieve databases.
In KDB.AI, a database is a collection of tables which stores related data.
Key principles for database management
To simplify database design/management and prevent naming conflicts, follow the principles below:
- Unique database names: Each database must have a unique name and can contain multiple tables.
- Unique table names within a database: Tables within a database must have unique names, but different databases can contain tables with the same name. This is similar to the concept of namespaces.
- Cascade deletion: When deleting a database, all child entities (tables) will also be deleted.
- Default database: You don't need to create a database to create tables. If you create a table without specifying a database, it will be placed in a default, undeletable database.
