Release 407-e LTS (28 Feb 2023)#

Starburst Enterprise platform (SEP) 407-e is the follow up release to the 406-e STS release and the 402-e LTS release.

This release is a long term support (LTS) release.

The 407-e release includes all improvements from the following Trino project releases:

It contains all improvements from the Starburst Enterprise releases since 402-e LTS:

Highlights since 402-e#

  • Added Run and troubleshoot to the query run options in the query editor.

  • Added SEP configuration validation that checks cluster configuration files for severe misconfigurations that can cause unwanted behavior.

  • Added table properties and schema properties entity types to built-in access control privileges.

  • Added support for DELETE in the MongoDB connector.

  • Expanded Fault-tolerant execution to support write operations on the MongoDB and BigQuery connectors, as well as exchange spooling in HDFS.

Breaking changes since 402-e#

  • SEP configuration validation now checks for catalog security misconfigurations that may cause security issues. If built-in access control is in use but a catalog is configured with the or configuration properties set to a value other than starburst, the cluster fails to start. The same failure occurs if the catalog configuration property is set to a value other than system. It is strongly recommended to fix this misconfiguration by setting all and properties to starburst and properties to system, but you may also disable configuration validation by setting starburst.config-validation.enabled=false in your file.

  • Built-in access control audit log now uses an improved backend schema for log storage. Existing log entries stored in the old schema are not automatically migrated to the new storage, so those older entries do not appear in the audit logs upon upgrading to this version of SEP.

  • The new SEP release requires usage of Trino Python client version 0.317 or newer.

  • The deprecated event-logger listener has been removed, and any SEP cluster configuration that uses this listener now fails to start. To resolve this, remove the configuration property from any configuration files.

  • If you use the Teradata direct connector, you must update the table operator. WARNING: This update is not backward-compatible. If you have multiple environments, such as a developement cluster, any cluster on a release before SEP 406-e is no longer able to connect to Teradata using the direct connector.
