本篇内容介绍了“MySQL普通表怎么转换成分区表”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
MySQL-5.7.32
对于业务繁忙的数据库来说，在运行了一定时间后，往往会产生一些数据量较大的表，特别是对于每天新增数据较多的日志表或者流水表，大表对于日常的运维非常的不方便，特别是数据的清理、迁移，表的访问性能也会随着数据量的增大而受到影响，因此，对于大表我们需要进行优化拆分，通常拆分的方案有
所以，通常选择分区表改造方案的主要原因都是为了避免应用层面的改造，对应用层面透明，以及方便日常的运维，前提是表具备改造分区条件。
参考文档
MySQL官方文档
1 根据业务的场景以及数据的分布，确认是否有匹配的分区表类型以及分区列
对于日志表，流水表这种按日期类型进行操作的，可以选择进行range分区
对于按用户ID类型的进行操作的，可以选择进行hash，key分区
对于按渠道，类型的进行操作的，可以选择进行list分区
2 应用涉及的sql，需要90%以上的操作都包含分区列，按分区操作，如果sql没有包含分区条件，扫描全分区，性能会出现下降。
查询表sql操作历史
select db,query,exec_count from sys.x$statement_analysis where lower(query) like '%%'order by exec_count;
3 主键必须包含分区键
4 分区键表达式只支持部分函数，存储过程，不支持二级制操作符以及/
5 分区不支持外键
查询表外键
select * from information_schema.KEY_COLUMN_USAGE where constraint_schema ='' and REFERENCED_TABLE_SCHEMA is not null\G
6 不支持查询缓存
7 5.7版本单个表分区最大支持8192个，并且会话第一次访问分区表，都需要打开全部的分区表，所以避免建立过多的分区
8 数据库最大文件打开数open_files_limit要设置足够大以满足表，分区的打开数量
9 数据库大文件large_files_support设置为on
10 分区列支持null值(对于rang分区，null值总小于任何的一个非null值，即存放在最左边的分区;对于list分区需要显示指定null值条件)，但从数据管理以及规范来看，不建议分区列存放null值，并且如果表有主键，则分区列不能为null值，因为分区列需要作为主键的一部分，不能为null
12 MySQL目前没有自动分区功能，所以需要监控分区的使用情况，通过job自动或者定时手动添加新分区
13 确定数据保留期限，定期归档分区数据
以下是一张数据量为766万的大表xxxx_user. xxxx_tab,计划将其改造为范围分区，按月存放。
select table_schema,table_name,table_rows,data_length/1024/1024/1024 from information_schema.tables where table_name='xxxx_tab';
表结构
CREATE TABLE `xxxx_tab` ( `ROLE_SEQ` bigint(20) NOT NULL , `PRD_ID` varchar(64) NOT NULL , `MAKE_RIGHT` varchar(1) DEFAULT '0' , `CHECK_RIGHT` varchar(1) DEFAULT '0' , `AUTH_RIGHT` varchar(1) DEFAULT '0' , `AUTH_GROUP` varchar(4) DEFAULT NULL , `RELEASE_RIGHT` varchar(1) DEFAULT '0' , `CREATE_USER_SEQ` bigint(20) DEFAULT NULL , `CREATE_DEPT_SEQ` bigint(20) DEFAULT NULL , `CREATE_TIME` datetime DEFAULT NULL , `UPDATE_USER_SEQ` bigint(20) DEFAULT NULL , `UPDATE_DEPT_SEQ` bigint(20) DEFAULT NULL , `UPDATE_TIME` datetime DEFAULT NULL , PRIMARY KEY (`PRD_ID`,`ROLE_SEQ`), KEY `xxxx_tab_IDX01` (`ROLE_SEQ`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4
分区列create_time日期最大值，最小值，根据这个范围按月创建分区
select max(CREATE_TIME),min(CREATE_TIME) from xxxx_tab;
分区列null值，对于存在的null值，需要应用对null数据进行处理，并且程序上需要确保数据写入not null
select count(*) from xxxx_tab where create_time is null;
主键重建添加分区列
alter table xxxx_tab drop primary key,add primary key (`PRD_ID`,`ROLE_SEQ`,`CREATE_TIME`);
由于主键没有包含分区列，需要重建主键添加分区列，对于主键重建我采取的是官方的online ddl功能，这种ddl操作会造成主从延时，但是不会产生大量的binlog，对于主从实时性要求高的，可以采用第三方的在线工具pt-osc,gh-ost
表转化为分区表
采用pt-osc在线将表转化为分区表，对于partition by 官方是不支持online ddl的，所以需要采用第三方的在线工具
./pt-online-schema-change --user=xxx --password=xxx --charset=utf8 D=xxxx_user,t=xxxx_tab --alter "PARTITION BY RANGE COLUMNS(CREATE_TIME)
