New Features & Improvements
Stored Procedures INOUT Parameters
- Stored procedures already have support for the IN, OUT and INOUT parameter qualifiers. Added as well for stored functions and (IN only) cursors (MDEV-10654). This was a contribution by ManoharKB.
Lag free ALTER TABLE in replication
- Normally, ALTER TABLE gets fully executed on the primary first and only then it is replicated and starts executing on replicas. With this feature
ALTER TABLEgets replicated and starts executing on replicas when it starts executing on the primary, not when it finishes. This way the replication lag caused by a heavy
ALTER TABLEcan be completely eliminated (MDEV-11675).
- Individual columns in the index can now be explicitly sorted in the ascending or descending order. This can be useful for optimizing certain ORDER BY cases (MDEV-13756, MDEV-26938, MDEV-26939, MDEV-26996).
InnoDB redo log improvements
- autosize innodb_buffer_pool_chunk_size (MDEV-25342).
- Improve the redo log for concurrency (MDEV-14425).
- Remove FIL_PAGE_FILE_FLUSH_LSN (MDEV-27199).
- Histograms in the statistics tables are more precise and stored as JSON, not binary (MDEV-21130, MDEV-26519, blog post).
Spider Storage Engine Improvements
- This was mostly internal refactoring work. As a result one can now declare Spider connections using the
REMOTE_TABLEattributes and not abuse the
COMMENTfield for that. This works both for the whole table and per partition (MDEV-5271, MDEV-27106).
- Add an optional argument to the CRC32() function, as well as the CRC32C() function, which uses the Castagnoli polynomial. (MDEV-27208). Note: The order of the 2-ary arguments was swapped after the preview release:
- Deprecate the keep_files_on_create variable (MDEV-23570).
- my_print_defaults now handles
--default-*options in exactly the same way as other MariaDB tools (MDEV-26238).
- UCA collations are now notably faster (MDEV-27266, MDEV-27265).
mysqlbinlog GTID support
- mariadb-binlog (or
mysqlbinlogas it was called back when the task was created) now supports both filtering events by GTID ranges through
--stop-position,and validating a binary log's ordering of GTIDs through
Windows - Improved i18n support
- On newer versions of Windows (Windows 10 1903 or later), the
mariadbclient defaults to the utf8mb4 character set. Several problems with Unicode input and output in client were fixed. Command line utilities now accept all Unicode characters in user names, database names, file names etc (in the past, characters were restricted to the current ANSI codepage).
