Notable Changes

  • Enterprise Spider no longer enables pushdown of UDFs and Stored Functions to the Data Node by default:

    • The default value of spider_use_pushdown_udf has changed from -1 to 0

    • In previous releases, Enterprise Spider pushed UDFs and Stored Functions down to the Data Node by default, which could cause query results to be inconsistent.

    • Starting with this release, all UDFs and stored functions are evaluated on the Spider Node by default. If desired, pushdown of UDFs and Stored Functions can be explicitly enabled by setting spider_use_pushdown_udf=1. Testing is recommended to confirm that query results are consistent. (MDEV-26545)

  • Performance Schema tables provide descriptions of each column in the COMMENT column option. (MDEV-25325)

  • Galera updated to 26.4.10

  • Debian 11 support added
