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#
Added support for PingIdentity as an OAuth 2.0 identity provider.
Added Managed statistics to the Redshift, Snowflake, MySQL, and SQL Server connectors as a public preview.
Added support for Fault-tolerant execution of write operations in SingleStore and IBM Db2.
Added query sharing to the Starburst Enterprise web UI query editor as a public preview.
Breaking changes since 407-e#
SEP now disallows setting
access-control.name=starburstas 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.enabledis not set to
config.propertieson 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
http-server.authentication.typeconfiguration 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
http-server.authentication.oauth2.groups-fieldproperty 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
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:
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:
This release introduced a Trino bug that causes some
INSERT INTO ... SELECTstatements 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-enabledconfiguration property to
fault_tolerant_execution_target_task_split_countconfiguration properties for Fault-tolerant execution are deprecated and must be removed from the
config.propertiesfile or the cluster does not start.
