We’re happy to announce the release of Trino 477, featuring two important updates to the Exasol connector:
-
Support for Exasol HASHTYPE
-
Performance improvements for queries using LIMIT and TOPN
These updates make workloads that limit result sets more efficient and expand type compatibility when accessing Exasol through Trino.
Recommended next steps:
-
If you run Exasol queries via Trino, we recommend first testing the upgrade to 477 in a staging environment.
-
Validate key dashboards and ETL jobs that use LIMIT or TOPN to confirm performance improvements.
-
Review any schemas using HASHTYPE to ensure type handling works as expected.
If you encounter issues or have feedback, please provide your Trino version, connector configuration, sample queries, and environment details. This helps us triage and respond more quickly.
