Data API

SingleStore provides the Data API to execute SQL statements against your database over an HTTP connection. The Data API can be used to integrate SingleStore with serverless architecture, develop custom applications, and build seamless integrations with applications.

SingleStore's Data API is authenticated to the server using the HTTP Basic and Bearer Authentication standards, which must be used in conjunction with SSL (HTTPS) for secure communication over the network. The Data API uses standard HTTP methods and response codes and supports URI versioning. It also uses JSON-encoded responses with support for conventional data type conversions. The Data API is accessible via a built-in HTTP server.

The Data API supports all SQL statements that can be run in a direct database connection with SingleStore Helios. To learn about the supported Data API endpoints, refer to Data API Endpoint Reference.

The Data API can support concurrent requests up to the value of the max_connection_threads engine variable. Refer to List of Engine Variables for more information.

SingleStore does not recommend updating or managing session-related entities using the Data API, for example, temporary tables, session variables, etc. Temporary tables created using the Data API are not automatically dropped when a connection is closed. Hence, you must explicitly drop any temporary tables created using the Data API before closing a connection (from within the same connection). To drop any temporary tables that exist after the connection is closed, kill the connection associated with that temporary table using the following commands:

-- Obtain the connection ID for the temporary table --
SHOW TEMPORARY TABLES;

-- Use the connection ID to kill the connection --
KILL CONNECTION <conn_ID>;
