Notable breaking changes#
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
DECODEfunction has been removed from the Oracle functions plugin. Users can change their SQL statements to achieve the same behavior with the use of a CASE statement.
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
Regular Kerberos support as as Kerberos and password authentication pass passthrough for the Teradata and Teradata Parallel Direct connectors it as available in prior releases is not included, but planned for a future patch version
Various configuration and property changes related to Kerberos configuration in general and specifically Kerberos credential pass-through
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.
