Release 380-e LTS (23 May 2022)#

Starburst Enterprise platform (SEP) 380-e is the follow up release to the 379-e STS release and the 370-e LTS release.

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

The 380-e release includes all improvements from the following Trino project releases:

It contains all improvements from the Starburst Enterprise releases since 370-e LTS:

Highlights since 370-e#

  • Add support for data products as securable entities with built-in access control.

  • Improve Kafka, PostgreSQL, Redshift, and Vertica connectors.

  • Add a session timeout configuration property for the Starburst Enterprise web UI.

  • Support two-way TLS for LDAP authentication.

  • Improve performance of queries involving complex predicates for the Teradata, Stargate, and PostgreSQL connectors.

  • Add autocomplete functionality for SQL in the query editor.

  • Add support for download of a full result set from the query editor.

  • Add an option to control the query log data retention period

Breaking changes since 370-e#

  • The SQL Server connector now enables TLS and certificate verification by default between the cluster and SQL Server, causing potential failures for catalogs that use the connector.

  • The ldap.ssl-trust-certificate configuration property for an LDAP password authenticator has been deprecated in favor of ldap.ssl.keystore.path and ldap.ssl.truststore.path for two-way TLS with an LDAP authentication server. Clusters that use the deprecated property in their LDAP password authenticator should migrate to the new properties as soon as possible.

  • Data products title length is now limited to 40 characters. Any existing data products with titles longer than 40 characters must be deleted and recreated.

  • Require value for the shared secret configuration for internal communication when any authentication is enabled.

  • The insights.authorized-users and insights.authorized-groups configuration properties are deprecated in favor of starburst.access-control.authorized-users and starburst.access-control.authorized-groups, respectively. These starburst. configuration properties also use a comma-separated list value, instead of a pipe-delineated list like the deprecated insights. properties. For more information, see Insights general configuration properties.

  • There are new format requirements for role names using built-in access controls. Role names with spaces must be replaced. Role names can have up to 64 characters, but can only contain lowercase Latin letters, digits, and underlines.

380-e.0 initial changes#

General#

Security#

  • Allow role creation only after specific role is set with SET ROLE.

  • Reintroduce ldap.ssl-trust-certificate as a legacy configuration property.

  • Update Helm chart to Starburst Ranger 2.1.0-e.39.

380-e.1 changes (8 Jun 2022)#

  • Standardize on UBI minimal base image for all containers used by the EKS listings.

  • Fix reading of grant change logs from SEP versions 375-e and earlier.

  • Fix potential query failure when metastore caching is enabled.

  • Fix typo in the configuration property name to remove an unsupported underscore and replace it with the appropriate dash DELEGATED-OAUTH2.

  • Fix sync_partition_metadata procedure failure when table has a large number of partitions.

  • Fix incorrect results for queries where aggregation is pushed down for a remote database to execute and the aggregation function result is not needed to evaluate the query. Applies to the ClickHouse, MariaDB, MySQL, Oracle, SQL Server, PostgreSQL, and SingleStore connectors.

380-e.2 changes (1 Jul 2022)#

  • Update jackson-databind to 2.13.3, see security advisory CVE-2020-36518.

  • Fix bigint parsing for the Web UI Query editor, no longer shows truncated results if it uses the default JSON.parse method.

  • Allow canceling a query on a transactional table if it is waiting for a lock.

  • Avoid errors when attempting to query tables that exist in multiple Snowflake databases with role impersonation enabled. The errors were a result of multiple tables matching the same schema/table name.

380-e.3 changes (1 Aug 2022)#

Important: In this release, we’ve patched a bug that causes the potential for incorrect results from certain queries that have had joins reordered in specific ways, in combination with certain data. A small percentage of queries are affected, but due to the complexity of the conditions that trigger the bug, it is not possible to predict which queries will be affected and thus we recommend that _all_ customers upgrade all clusters.

  • Fix incorrect results for certain join queries containing filters involving explicit or implicit casts.

  • Add Varbinary handling to Kafka Protobuf deserializer.

  • Fix initialization failure when the internal table snapshots cache is disabled. Applicable to the Delta Lake connector.

  • Fix incorrect query results when reading a Delta Lake table with a cached representation of its active data files that are outdated.

  • Fix certain complex queries that involve joins and aggregations.

  • Fix incorrect results when using the Glue metastore and queries contain IS NULL with additional filters. Applicable to Hive, Iceberg, and Delta connectors.

  • Fix incorrect pushdown of expression below join.

380-e.4 was skipped.

380-e.5 changes (9 Sep 2022)#

  • Fix issue with live queries being filtered incorrectly.

  • Fix writing incorrect results in the Delta Lake connector when the order of partition columns is different from the order in the table definition

  • Fix incorrect table already exists error in the Delta Lake connector caused by a client timeout when creating a new table.

  • Fix bug in the Hive connector where query constraints were not used when fetching table statistics.

  • Fix Teradata pushdown correctness for char types.

380-e.6 changes (26 Sep 2022)#
