MariaDB数据库
MariaDB基于事务的Maria存储引擎,替换了MySQL的MyISAM存储引擎,它使用了Percona的 XtraDB,InnoDB的变体,分支的开发者希望提供访问即将到来的MySQL 5.4 InnoDB性能。这个版本还包括了 PrimeBase XT (PBXT) 和 FederatedX存储引擎。
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:
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.
