25.12.11.1 The replication_connection_configuration Table

This table shows the configuration parameters used by the slave server for connecting to the master server. Parameters stored in the table can be changed at runtime with the CHANGE MASTER TO statement, as indicated in the column descriptions.

Compared to the replication_connection_status table, replication_connection_configuration changes less frequently. It contains values that define how the slave connects to the master and that remain constant during the connection, whereas replication_connection_status contains values that change during the connection.

The replication_connection_configuration table has the following columns. The column descriptions indicate the corresponding CHANGE MASTER TO options from which the column values are taken, and the table given later in this section shows the correspondence between replication_connection_configuration columns and SHOW SLAVE STATUS columns.

TRUNCATE TABLE is not permitted for the replication_connection_configuration table.

The following table shows the correspondence between replication_connection_configuration columns and SHOW SLAVE STATUS columns.
