New Features
Temporary files and tables
- Limit size of created disk temporary files and tables (MDEV-9101)
- There are two system variables used for controlling this feature:
- max_tmp_session_space_usage: Limits the the temporary space allowance per user.
- max_tmp_total_space_usage: Limits the temporary space allowance for all users.
Data Types
- The TIMESTAMP range of values was extended. The maximal allowed value for timestamps was '2038-01-19 03:14:07 UTC', and is now '2106-02-07 06:28:15 UTC'. This does not change the storage format, and new tables can be read by old MariaDB servers as long as timestamp values are within the old timestamp range. At the moment this is only supported on 64-bit platforms (MDEV-32188).
Optimizer
- Index condition pushdown is now supported for partitioned tables (MDEV-12404)
- ANALYZE FORMAT=JSON now shows selectivity of pushed index condition (MDEV-18478)
Protocol
- Permit bulk implementation to return ALL individual results (MDEV-30366)
- Send initial values of system variables in first OK packet (MDEV-31609)
Observability
- New USERS table in the Information Schema for storing information about users, password expiry, and the limits set by max_password_errors (MDEV-23729, MDEV-32218)
- Add more columns to Information Schema TABLE_STATISTICS, CLIENT_STATISTICS and USER STATISTICS tables (MDEV-33151)
- Add QUERIES column to Information Schema INDEX_STATISTICS table (MDEV-33152)
- Add FLUSH GLOBAL STATUS (MDEV-33145)
- Provide InnoDB async IO statistics (MDEV-32841)
- Show variable deprecation for mariadbd --help output (MDEV-28671)
- Extend Query Response Time plugin to be compatible with Percona server (MDEV-33501)
Sequences
- Additional features for Sequences (MDEV-28152)
- CREATE SEQUENCE ... AS permits creating as any INT type (including BIGINT UNSIGNED), extending the range
- Information Schema Sequences table
- Parser accepts larger and smaller values for MINVALUE and MAXVALUE
- ANALYZE TABLE on sequences no longer attempts to collect statistics (MDEV-33938)
Other
- REPAIR TABLE ... FORCE (MDEV-33449)
- Introduce the innodb_log_spin_wait_delay system variable to address excessive context switching caused by log_sys.lsn_lock (observed on write-intensive workloads on NUMA systems) (MDEV-33515)
- Deprecate and ignore the alter_algorithm system variable (MDEV-33655)
- Change default Unicode collation to uca1400_ai_ci (MDEV-25829)
- Parallel dump of multiple databases via mariadb-dump with the
--diroption (MDEV-33625) - Deprecate spider_casual_read (MDEV-31789)
