Release 426-e STS (18 Sep 2023)#

Starburst Enterprise platform (SEP) 426-e is the follow up release to the 423-e version. It includes all improvements from the following Trino releases:

This release is a short term support (STS) release.

Breaking changes#

The SEP backend service has been updated to require PostgreSQL 12.0+ when using PostgreSQL as the underlying RDBMS.
TIMESTAMP type mapping between MySQL and Trino is no longer TIMESTAMP to TIMESTAMP. The new conversion is MySQL TIMESTAMP to Trino TIMESTAMP WITH TIMEZONE. Depending on the query, mapping from MySQL TIMESTAMP to Trino TIMESTAMP may result in an error message.
Privileged access to the attached storage on nodes is no longer required for Starburst Warp Speed cluster configuration in Helm deployments. Existing cluster configurations must be updated, with EKS deployments requiring the addition of a bootstrap script. Review and follow the considerations for your platform in the Starburst Warp Speed documentation.
The deprecated.hive.metastore.glue-read-properties-based-column-statistics Hive Metastore configuration property and underlying functionality has been removed. You must remove this configuration property or the cluster fails to start.

General#

Switched Starburst Warp Speed to use filesystem-based storage, to remove the requirement for privileged access to attached storage.

Security#

Added the lake-formation.max-connections configuration property for AWS Lake Formation.
Added support for credential vending for reading AWS Lake Formation tables.

Hive connector#

Added a new hive.trino-views.run-as-invoker catalog configuration property to only execute views in INVOKER mode.

Splunk connector#

Added support for predicate pushdown on BOOLEAN, INTEGER, BIGINT, DOUBLE, VARCHAR, and TIMESTAMP(3) types.
