Azat Khuzhin	a61a6b9f51	Add settings (for connections) for MySQL storage engine ... Default settings are not very efficient, since they do not even reuse connections. And when each query requires connection you can have only ~80 QPS, while by simply enabling connection reuse (connection_auto_close=false) you can have ~500 QPS (and by increasing connection_pool_size you can have better QPS throughput). So this patch allows to pass through some connection related settings for the StorageMySQL engine, like: - connection_pool_size=16 - connection_max_tries=3 - connection_auto_close=true v2: remove connection_pool_default_size v3: remove num_tries_on_connection_loss	2021-05-20 22:44:52 +03:00
