Constructor & Destructor Documentation

DatabaseMysqlBase::__construct ( array  $params)

Additional $params include:

  • lagDetectionMethod : set to one of (Seconds_Behind_Master,pt-heartbeat). pt-heartbeat assumes the table is at heartbeat.heartbeat and uses UTC timestamps in the heartbeat.ts column. (https://www.percona.com/doc/percona-toolkit/2.2/pt-heartbeat.html)
  • lagDetectionOptions : if using pt-heartbeat, this can be set to an array map to change the default behavior. Normally, the heartbeat row with the server ID of this server's master will be used. Set the "conds" field to override the query conditions, e.g. ['shard' => 's1'].
  • useGTIDs : use GTID methods like MASTER_GTID_WAIT() when possible.
  • sslKeyPath : path to key file [default: null]
  • sslCertPath : path to certificate file [default: null]
  • sslCAPath : parth to certificate authority PEM files [default: null]
  • sslCiphers : array list of allowable ciphers [default: null]
    Parameters
    array$params
