List the tables that ain’t support Galera Cluster

Basically, if you want to have your DB serve by Galera cluster, you have to use InnoDB storage engine and define a primary key for each table.

To indentify which table are not good to go with Galera clustr, you can run following SQL query:

SELECT DISTINCT
     CONCAT(t.table_schema,'.',t.table_name) as tbl,
     t.engine,
     IF(ISNULL(c.constraint_name),'NOPK','') AS nopk,
     IF(s.index_type = 'FULLTEXT','FULLTEXT','') as ftidx,
     IF(s.index_type = 'SPATIAL','SPATIAL','') as gisidx
FROM information_schema.tables AS t
LEFT JOIN information_schema.key_column_usage AS c
  ON (t.table_schema = c.constraint_schema AND t.table_name = c.table_name
      AND c.constraint_name = 'PRIMARY')
LEFT JOIN information_schema.statistics AS s
  ON (t.table_schema = s.table_schema AND t.table_name = s.table_name
      AND s.index_type IN ('FULLTEXT','SPATIAL'))
WHERE t.table_schema NOT IN ('information_schema','performance_schema','mysql')
  AND t.table_type = 'BASE TABLE'
  AND (t.engine <> 'InnoDB' OR c.constraint_name IS NULL OR s.index_type IN ('FULLTEXT','SPATIAL'))
ORDER BY t.table_schema,t.table_name;
