## AI overview

The article describes a refresh of Trino's file-system caching in the Trino 439 release. The new Alluxio-powered caching benefits catalogs using the Delta Lake, Hive, Iceberg, and planned Hudi connectors, replacing the outdated RubiX-based approach through extensive community collaboration.

## Source excerpt

Thinking about our recent work on caching in Trino reminds me of the famous saying, "There are only two hard things in computer science: cache invalidation and naming things." Well, in the Trino community we know all about caching and naming. With the recent Trino 439 release, caching from object storage file systems got a refresh. Catalogs using the Delta Lake, Hive, Iceberg, and soon Hudi connectors now get to access performance benefits from the new Alluxio-powered file system caching.
