By default, MySQL itself breaks links through various timeout parameters.
Various interpretations of the timeout:
Connect_timeout is useful when establishing a connection, and is recommended for use with connection pooling or for poor network conditions. Interactive_timeout and wait_timeout Interactive and non-interactive links are primarily applicable to connection idle stages. Net_read_timeout and net_write_timeout are mainly connection timeouts d
