TrinoHub 0.2.0

Released 20 July 2026 · GitHub release

First tagged release.

Added#

• Query result caching. Automatic, per-user caching of repeated read-only queries, with a configurable TTL and a Run fresh bypass. Cache status is shown in results, history, query profiles, Ask Trino, and MCP responses. Eligible cached results are served without waking an auto-suspended cluster.
• Automated, version-checked GitHub release workflow and a maintainer release checklist.

Security#

• Cached data is invalidated after user, role, policy, catalog, cluster, tag, and write mutations, so caching cannot outlive the grants it was read under.

Upgrading#

New CloudFormation installations pin to the immutable v0.2.0 release. Existing instances upgrade through SSM — see the AWS upgrade guide. Back up .trinohub/ first.
