Release 332-e LTS (14 Apr 2020)#
Starburst Enterprise Presto 332-e is the follow up release to the 323-e version.
The 332-e release includes all improvements from the Presto project releases since Presto 323:
This release is a long term support (LTS) release.
In addition, numerous improvements and additions for enterprise features are added:
Apache Ranger as a service in both CFT and K8s

Added support for parallel operations to the Oracle connector
The internal cluster communication in earlier Starburst Enterprise Presto supports using Kerberos for authentication. This functionality has been removed in favor of automatically securing internal cluster communication. Find more details in Secure Internal Communication.
The Starburst BigQuery connector is replaced by the open source BigQuery connector contributed by the community. The new connector is more feature-rich and performant. Users of the old connector need to change their catalog files to adapt to the usage of the new connector and its configuration properties, documented in BigQuery Connector.
The usage of
groupsin resource groups as selector rule properties and used for catalog rules as part of the built-in system access controls is deprecated. Replace any usage with lists and regular expressions in the
groupfields. For example, change
users: ["abc", "def", "xyz"]to
The Starburst Secrets support using a Java keystore file containing any secrets is deprecated and replaced with the secrets support from Presto. More information can be found in Secrets.
The query audit feature changed to use a different configuration file and properties.
Configuration of the path to the license for Starburst Enterprise Presto changed to use a default path. As a result, the
license.pathproperty has been removed entirely.
Ranger-based audit as available in prior releases is included from 332-e.2 onwards only

The preferred runtime for Presto servers changes from Java 8 to Java 11. While using Java 11 is not a hard requirement at this stage, we strongly suggest to update to gain performance improvements and other benefits. Java 11 is planned as a hard requirement for the next release. More information can be found in in the Java requirements section.
