Release 413-e LTS (30 May 2023)#

Starburst Enterprise platform (SEP) 413-e LTS is the follow up release to the 413-e STS release and the 407-e LTS release.

This release is a promotion of the original 413-e STS release in April 2023 into a long term support (LTS) release.

The 413-e release includes all improvements from the following Trino project releases:

It contains all improvements from the Starburst Enterprise releases since 407-e LTS:

Highlights since 407-e#

Breaking changes since 407-e#

  • SEP now disallows setting access-control.name=starburst as an access control system when built-in access control is not enabled on the coordinator. If this property is configured in an access control properties file but starburst.access-control.enabled is not set to true in config.properties on the coordinator node, the cluster fails to start.

  • Upgrades to this release involve an automated migration in the backend service database. If the cluster fails to start with an error message Migration of schema "public" to version "413.2 - Category" failed, contact Starburst Support for assistance.

  • SEP configuration validation now verifies that there is no combination of insecure and secure authentication types between the web-ui.authentication.type and http-server.authentication.type configuration properties. If this validation fails, the cluster fails to start and a descriptive error message appears. It is strongly recommended to fix this misconfiguration by setting both configuration properties to secure authentication types. You may also disable configuration validation by setting starburst.config-validation.enabled=false in your config.properties file.

  • The http-server.authentication.oauth2.groups-field property was renamed to deprecated.http-server.authentication.oauth2.groups-field. You must update the property name, or the cluster fails to start.

  • The accelerated Parquet reader was removed, and replaced with an improved implementation in Trino. The catalog configuration properties iceberg.accelerated-parquet-reader.enabled, hive.accelerated-parquet-reader.enabled, and delta.accelerated-parquet-reader.enabled, and the related catalog session properties are deprecated and must be removed from catalog configurations or the cluster does not start. The new implemenetation is enabled by default, see Parquet format configuration properties for details applicable to all object storage connectors.

  • The following connector names have been removed and must be changed to allow successful cluster starts:

    • hive-hadoop2 to hive

    • memsql to singlestore

  • The following connector names have been changed. The old connector names continue to work but it is strongly recommended to change catalog configurations to the new names:

    • delta-lake to delta_lake

    • generic-jdbc to generic_jdbc

    • sap-hana to sap_hana

    • snowflake-jdbc to snowflake_jdbc

    • snowflake-distributed to snowflake_distributed

    • teradata-direct to teradata_direct

    • warp-speed to warp_speed

  • This release introduced a Trino bug that causes some INSERT INTO ... SELECT statements to fail with an “invalid offset” exception when exchange data compression is enabled as part of a Fault-tolerant execution configuration. For a temporary workaround, set the exchange.compression-enabled configuration property to false.

  • The fault_tolerant_execution_target_task_input_size and fault_tolerant_execution_target_task_split_count configuration properties for Fault-tolerant execution are deprecated and must be removed from the config.properties file or the cluster does not start.
