Il plugin QUERY_CACHE_INFO

MariaDB starting with 5.5.31

Questo plugin è stato introdotto in MariaDB 5.5.31

Il plugin QUERY_CACHE_INFO permette di visualizzare i contenuti della cache delle query. Crea una tabella nel database INFORMATION_SCHEMA che mostra tutte le query che si trovano nella cache. Per accedere a questa tabella occorre il privilegio PROCESS (si veda GRANT).

MariaDB [test]> select statement_schema, statement_text, result_blocks_count,
   --> result_blocks_size from information_schema.query_cache_info;
+------------------+------------------+---------------------+--------------------+
| statement_schema | statement_text   | result_blocks_count | result_blocks_size |
+------------------+------------------+---------------------+--------------------+
| test             | select * from t1 |                   1 |                512 |
