Notable Changes

• Lots of changes related to encryption. See the updated documentation. In particular:
  • The distinction between “tablespace encryption” and “page encryption” was removed, now there is only one single encryption feature. One can use both per-table encryption options and the global innodb-encrypt-tables option at the same time.
  • Per table PAGE_ENCRYPTION option that could accept values of ON and OFF was renamed to ENCRYPTED with values YES and NO.
  • Per table PAGE_ENCRYPTION_KEY was renamed to ENCRYPTION_KEY_ID.
  • Global variable innodb_default_page_encryption_key become a session innodb_default_encryption_key_id.
  • The command-line option innodb-encrypt-tables can take the value of FORCE. In this case XtraDB/InnoDB will refuse to create unencrypted tables (CREATE TABLE ... ENCRYPTED=NO will fail).
  • XtraDB/InnoDB on disk format for encrypted tablespaces and logs was changed. Tables encrypted in 10.1.3 may fail to open.
  • Key management plugins were renamed not to have “plugin” in the name, for example, “file_key_management_plugin” is now “file_key_management”.
  • “Key management plugin” type was expanded and renamed to match the new broader set of responsibilities. It is now called encryption plugin.

• Command-line option innodb-scrub-log-interval was renamed to innodb-scrub-log-speed and now sets the log scrubbing speed in bytes per second.
• Command-line option innodb-scrub-force-testing was renamed to innodb-debug-force-scrubbing.

• Consistent support for IF EXISTS, IF NOT EXISTS, and OR REPLACE clauses was added to:
  • CREATE EVENT and DROP EVENT (MDEV-7281)
  • CREATE INDEX and DROP INDEX (MDEV-7284)
  • CREATE TRIGGER and DROP TRIGGER (MDEV-7286)

• MDEV-5214 New status variables to show the number of grants on different objects (see Status Variables Added in MariaDB 10.1).
• MDEV-6858 New server variable enforce_storage_engine
• MDEV-7728 xid cache scalability was significantly improved (by using lock-free hash)
• MDEV-7671 VIEW definitions are now cached in memory (in the table definition cache).
• MDEV-6981 New status variables to track MASTER_GTID_WAIT time. This feature was contributed by Daniel Black. See Status Variables Added in MariaDB 10.1.
• MDEV-7198 New status variable Slave_skipped_errors. This feature was contributed by Daniel Black.
• Starting with this release, commits in certain instances in parallel replication complete immediately, avoiding losing throughput when many transactions need conflicting locks. See binlog_commit_wait_count.
• MDEV-7061 innochecksum can now analyze leaf pages to estimate how fragmented an index is and how much benefit can be gained from defragmentation.
