MySQL 5.7 Reference Manual  /  ...  /  The replication_applier_status_by_coordinator Table The replication_applier_status_by_coordinator Table

For a multi-threaded slave, the slave uses multiple worker threads and a coordinator thread to manage them, and this table shows the status of the coordinator thread. In MySQL 5.7.9 and later, for a single-threaded slave, this table is empty. (Previously, this table showed the applier thread status for a single-threaded slave; this information can now be found in the replication_applier_status_by_worker table in such cases. See Bug #74765, Bug #20001173.) This table was added in MySQL 5.7.2 as replication_execute_status_by_coordinator, and renamed replication_applier_status_by_coordinator in MySQL 5.7.6. For a multi-threaded slave, the replication_applier_status_by_worker table shows the status of the worker threads.

The replication_applier_status_by_coordinator table has these columns:


    The replication channel which this row is displaying. There is always a default replication channel, and more replication channels can be added. See Section 18.2.3, “Replication Channels” for more information.


    The SQL/coordinator thread ID.


    ON (thread exists and is active or idle) or OFF (thread no longer exists).


    The error number and error message of the most recent error that caused the SQL/coordinator thread to stop. An error number of 0 and message of the empty string mean no error. If the LAST_ERROR_MESSAGE value is not empty, the error values also appear in the slave's error log.

    Issuing RESET MASTER or RESET SLAVE resets the values shown in these columns.

    All error codes and messages displayed in the LAST_ERROR_NUMBER and LAST_ERROR_MESSAGE columns correspond to error values listed in Section B.3, “Server Error Codes and Messages”.


    A timestamp in YYMMDD HH:MM:SS format that shows when the most recent SQL/coordinator error occurred.

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