Performance Schema Replication Tables The port used to connect to the source. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_PORT , CHANGE MASTER TO  option:  MASTER_PORT ) The user name of the replication user account used to connect to the source. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_USER ,  CHANGE MASTER TO  option:  MASTER_USER ) The network interface that the replica is bound to, if any. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_BIND ,  CHANGE MASTER TO  option:  MASTER_BIND ) 1 if GTID auto-positioning is in use; otherwise 0. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_AUTO_POSITION ,  CHANGE MASTER TO  option:  MASTER_AUTO_POSITION ) These columns show the SSL parameters used by the replica to connect to the source, if any. SSL_ALLOWED  has these values: ( CHANGE REPLICATION SOURCE TO  options for the other SSL columns:  SOURCE_SSL_CA , SOURCE_SSL_CAPATH ,  SOURCE_SSL_CERT ,  SOURCE_SSL_CIPHER ,  SOURCE_SSL_CRL , SOURCE_SSL_CRLPATH ,  SOURCE_SSL_KEY ,  SOURCE_SSL_VERIFY_SERVER_CERT . CHANGE MASTER TO  options for the other SSL columns:  MASTER_SSL_CA ,  MASTER_SSL_CAPATH , MASTER_SSL_CERT ,  MASTER_SSL_CIPHER ,  MASTER_SSL_CRL ,  MASTER_SSL_CRLPATH , MASTER_SSL_KEY ,  MASTER_SSL_VERIFY_SERVER_CERT . The number of seconds between connect retries. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_CONNECT_RETRY ,  CHANGE MASTER TO  option:  MASTER_CONNECT_RETRY ) The number of times the replica can attempt to reconnect to the source in the event of a lost connection. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_RETRY_COUNT ,  CHANGE MASTER TO  option: MASTER_RETRY_COUNT ) The replication heartbeat interval on a replica, measured in seconds. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_HEARTBEAT_PERIOD ,  CHANGE MASTER TO  option: MASTER_HEARTBEAT_PERIOD ) 5001 • HEARTBEAT_INTERVAL • TLS_VERSION • CONNECTION_RETRY_COUNT • CONNECTION_RETRY_INTERVAL • Yes  if an SSL connection to the source is permitted • No  if an SSL connection to the source is not permitted • Ignored  if an SSL connection is permitted but the replica does not have SSL support enabled • SSL_ALLOWED ,  SSL_CA_FILE ,  SSL_CA_PATH ,  SSL_CERTIFICATE ,  SSL_CIPHER ,  SSL_KEY , SSL_VERIFY_SERVER_CERTIFICATE ,  SSL_CRL_FILE ,  SSL_CRL_PATH • AUTO_POSITION • NETWORK_INTERFACE • USER
