22.214.171.124 SHOW RELAYLOG EVENTS Statement
SHOW RELAYLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count] [channel_option] channel_option: FOR CHANNEL channel
Shows the events in the relay log of a replica. If you do not specify
', the first relay log is displayed. This statement has no effect on the source.
SHOW RELAYLOG EVENTS requires the
REPLICATION SLAVE privilege.
SHOW RELAYLOG EVENTS with no
LIMIT clause could start a very time- and resource-consuming process because the server returns to the client the complete contents of the relay log (including all statements modifying data that have been received by the replica).
FOR CHANNEL clause enables you to name which replication channel the statement applies to. Providing a
FOR CHANNEL clause applies the statement to a specific replication channel. If no channel is named and no extra channels exist, the statement applies to the default channel.
When using multiple replication channels, if a
SHOW RELAYLOG EVENTS statement does not have a channel defined using a
FOR CHANNEL clause an error is generated. See Section 16.2.3, “Replication Channels” for more information.
SHOW RELAYLOG EVENTS displays the following fields for each event in the relay log:
The name of the file that is being listed.
The position at which the event occurs.
An identifier that describes the event type.
The server ID of the server on which the event originated.
The value of
End_log_posfor this event in the source's binary log.
More detailed information about the event type. The format of this information depends on the event type.
