MySQL/MariaDB数据库的复制过滤器
MySQL/MariaDB数据库的复制过滤器

一.复制过滤器概述
1>.复制器过滤器功能
让从节点仅复制指定的数据库，或指定数据库的指定表。
2>.两种实现方式
方案一:
主服务器仅向二进制日志中记录与特定数据库相关的事件
此项和binlog_format相关,详情请参考官网说明:https://mariadb.com/kb/en/library/mysqld-options/#-binlog-ignore-db
binlog_do_db = 数据库白名单列表，多个数据库需多行实现
binlog_ignore_db = 数据库黑名单列表
问题：
基于二进制还原将无法实现(因为记录的日志只有部分数据库信息，可能存在部分数据无法还原的现象)；不建议使用 方案二:
从服务器SQL_THREAD在replay中继日志中的事件时，仅读取与特定数据库(特定表)相关的事件并应用于本地
问题：
由于将master节点的所有数据都copy至slave节点,但SQL_THREAD线程仅读取与特定数据库(特定表)相关的事件并应用于本地,也就是说部分数据传过来也不去使用，这会造成网络及磁盘IO浪费。
3>.从服务器上的复制过滤器相关变量
MariaDB [(none)]> SHOW VARIABLES LIKE '%replicate%';
+----------------------------------+-----------+
| Variable_name | Value |
+----------------------------------+-----------+
| replicate_annotate_row_events | OFF |
| replicate_do_db | |
| replicate_do_table | |
| replicate_events_marked_for_skip | replicate |
| replicate_ignore_db | |
| replicate_ignore_table | |
| replicate_wild_do_table | |
| replicate_wild_ignore_table | |
+----------------------------------+-----------+
rows in set (0.00 sec) MariaDB [(none)]>
MariaDB [(none)]> SHOW VARIABLES LIKE '%replicate%';
replicate_do_db=
指定复制库的白名单
replicate_ignore_db=
指定复制库黑名单
replicate_do_table=
指定复制表的白名单
replicate_ignore_table=
指定复制表的黑名单
replicate_wild_do_table= foo%.bar%
解决跨库更新的问题支持通配符
replicate_wild_ignore_table=
同上
