-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
MySQL was started within the last 24 hours: recommendations may be inaccurate
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See https://dev.mysql.com/doc/internals/en/join-buffer-size.html
(specially the conclusions at the bottom of the page).
Be careful, increasing innodb_redo_log_capacity means higher crash recovery mean time
Variables to adjust:
join_buffer_size (> 256.0K, or always use indexes with JOINs)
innodb_buffer_pool_size (>= 2.7G) if possible.
innodb_redo_log_capacity should be (=32M) if possible, so InnoDB Redo log Capacity equals 25% of buffer pool size.
ローカルで起動したMySQLコンテナに対して、MySQL Tunerを実行した結果↓
ある程度稼働しているMySQLに対して実行した方が良いので、あまり参考にならないかもしれない。 とりあえず下記は対応してみても良いかもしれない。
