MariaDB 10.1.4 发布了,下载地址: https://downloads.mariadb.org/mariadb/10.1.4/

这是 MariaDB 10.1 的第二个 Beta 测试版本,也是第 5 个发行版本,该版本值得关注的改进内容包括:

  • Encryption:很多跟表和表空间加密的改变在该版本得以实现,详情请看 updated documentation 和 nice summarization here

  • Consistent support for IF EXISTS, IF NOT EXISTS, and OR REPLACE clauses was added to:

    • CREATE EVENT and DROP EVENT

    • CREATE INDEX and DROP INDEX

    • CREATE TRIGGER and DROP TRIGGER

  • New server variable:New server variable enforce_storage_engine

  • New status variable:New status variables to show the number of grants on different objects (Also see Status Variables Added in MariaDB 10.1 )

  • New status variable:New status variables to track MASTER_GTID_WAIT time. This feature was contributed by Daniel Black.

  • New status variable:New status variable Slave_skipped_errors . This feature was contributed by Daniel Black.

  • Performance: xid cache scalability was significantly improved (by using lock-free hash)

  • Performance: VIEW definitions are now cached in memory (in the table definition cache)

  • Replication: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 .
