Administration
The following documents cover a number of different aspect of configuring, running, and managing Trino clusters.
Details about connecting data sources as catalogs are available in the connector documentation.
Event listeners
Event listeners are plugins that allow streaming of query events, such as query started or query finished, to an external system.
Using an event listener you can process and store the query events in a separate system for long periods of time. Some of these external systems can be queried with Trino for further analysis or reporting.
The following event listeners are available:
Unrelated to event listeners, the coordinator stores information about recent
queries in memory for usage by the Web UI - see also
query.max-history and query.min-expire-age in
Query management properties.
