Step1: ===== Backport 'replication_applier_status_by_worker' from upstream. Iterate through rpl_parallel_thread_pool and display slave worker thread specific information as part of 'replication_applier_status_by_worker' table. --------------------------------------------------------------------------- |Column Name: | Description: | |-------------------------------------------------------------------------| | | | |CHANNEL_NAME | Name of replication channel through which the | | | transaction is received. | | | | |THREAD_ID | Thread_Id as displayed in 'performance_schema. | | | threads' table for thread with name | | | 'thread/sql/rpl_parallel_thread' | | | | | | THREAD_ID will be NULL when worker threads are | | | stopped due to an error/force stop | | | | |SERVICE_STATE | Thread is running or not | | | | |LAST_SEEN_TRANSACTION | Last GTID executed by worker | | | | |LAST_ERROR_NUMBER | Last Error that occured on a particular worker | | | | |LAST_ERROR_MESSAGE | Last error specific message | | | | |LAST_ERROR_TIMESTAMP | Time stamp of last error | | | | --------------------------------------------------------------------------- CHANNEL_NAME will be empty when the worker has not processed any transaction. Channel_name points to valid source channel_name when it is processing a transaction/event group.
