Highlights since 468-e#

Breaking changes#

  • The minimum required Java runtime for the JDBC driver and CLI has been updated to Java 11. If you are using an earlier version, you must upgrade to Java 11 or later.

  • The optimize_hash_generation session property and the optimizer.optimize-hash-generation configuration option have been removed. You must remove these properties from your configuration or the cluster fails to start.

  • The following Unity catalog metastore configuration properties have been renamed in the Delta Lake connector:

    • delta.metastore.unity.host to hive.metastore.unity.host

    • delta.metastore.unity.catalog-name to hive.metastore.unity.catalog-name

    • delta.metastore.unity.access-token to hive.metastore.unity.token

    Update these properties in your catalog configuration file or the cluster fails to start.

  • The Kinesis connector has been removed. Update your dependencies and configurations to use an alternative connector.

  • The following HTTP client property prefixes have been renamed:

    • workerInfo to worker-info

    • memoryManager to memory-manager

    If you use these properties in your configuration files, the old names are no longer recognized. Update your configurations to use the new names to avoid unexpected behavior.

  • The following Hive metastore HTTP client properties have been removed:

    • hive.metastore.http.client.additional-headers

    • hive.metastore.http.client.authentication.type

    • hive.metastore.http.client.bearer-token

    • hive.metastore.http.client.read-timeout

    If your current configuration includes any of these properties, update your configuration to remove them. If left in place, you may experience connection and authentication issues when interacting with the Hive metastore.

  • Effective May 23, 2025, AWS Glue no longer allows modifying the table_type parameter of an existing table. Any attempt to update an existing table’s table_type, such as migration procedures, results in a validation error from AWS Glue. If you wish to change the table_type parameter, you must use a CTAS operation to create a new table with the desired table_type. Rename the new table to match the original table name and adjust dependent resources as needed.

  • The Phoenix connector has been removed due to incompatibility with Java 24. If your setup uses this connector, you must update your configuration to use an alternative supported connector.

  • The following dynamic filtering properties have been removed:

    • dynamic-filtering.large-partitioned.range-row-limit-per-driver

    • dynamic-filtering.large.range-row-limit-per-driver

    • dynamic-filtering.small-partitioned.range-row-limit-per-driver

    • dynamic-filtering.small.range-row-limit-per-driver

    If your current configuration includes any of these properties, update your configuration to remove them.

  • The Custom Resource Definitions (CRDs) for the External Secrets Operator included in the SEP Helm Chart have been updated from v1beta1 to v1. Upgrade your External Secrets Operator to v0.17, which fully supports v1.
