既存のテーブルが Group Replication に準拠してるか

  • エンジンが InnoDB であることが必要
  • Primary Key が必須だよ

エンジンが InnoDB かどうか

SELECT table_schema, table_name, engine, table_rows,
(index_length+data_length)/1024/1024 AS sizeMB
FROM information_schema.tables
WHERE engine != 'innodb'
AND table_schema NOT IN
('information_schema', 'mysql', 'performance_schema');

テーブル構造が Group Replication 準拠か

SELECT tables.table_schema , tables.table_name , tables.engine
FROM information_schema.tables
LEFT JOIN (
SELECT table_schema , table_name
FROM information_schema.statistics
GROUP BY table_schema, table_name, index_name HAVING
SUM( case when non_unique = 0 and nullable != 'YES' then 1 else 0 end ) = count(*) ) puks
ON tables.table_schema = puks.table_schema and tables.table_name = puks.table_name
WHERE puks.table_name is null
AND tables.table_type = 'BASE TABLE' AND Engine="InnoDB";
