SHOW RELAYLOG EVENTS [IN 'log_name
'] [FROMpos
] [LIMIT [offset
,]row_count
]
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.
log_name
'
The LIMIT
clause has the same syntax as for
the SELECT
statement. See
Section 13.2.9, “SELECT Statement”.
Issuing a 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).
SHOW RELAYLOG EVENTS
displays the
following fields for each event in the relay log:
Log_name
The name of the file that is being listed.
Pos
The position at which the event occurs.
Event_type
An identifier that describes the event type.
Server_id
The server ID of the server on which the event originated.
End_log_pos
The value of End_log_pos
for this event
in the source's binary log.
Info
More detailed information about the event type. The format of this information depends on the event type.
Some events relating to the setting of user and system
variables are not included in the output from
SHOW RELAYLOG EVENTS
. To get
complete coverage of events within a relay log, use
mysqlbinlog.
