Metadata Streams

Metadata streams are automatically created by Event Stream Processor. Query and subscribe to these streams to obtain important health and performance information about the currently running project.

Some metadata streams contain static information that never change while the project is running, for example, _esp_streams. Other streams continuously update at various periods or on various events. You can subscribe, query, and view metadata streams in the same way as regular streams.

Note: The schema for metadata streams can change between releases as the set of statistics the streams report expands. New columns are added to the end of the schema for existing metadata streams. Keep this in mind when coding.
