SHOW RELAYLOG EVENTS
The terms master and slave have historically been used in replication, but the terms terms primary and replica are now preferred. The old terms are used still used in parts of the documentation, and in MariaDB commands, although MariaDB 10.5 has begun the process of renaming. The documentation process is ongoing. See MDEV-18777 to follow progress on this effort.
SHOW RELAYLOG ['connection_name'] EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count] [ FOR CHANNEL 'channel_name']
Syntax for the
LIMIT clause is the same as for SELECT ... LIMIT.
LIMIT clause is highly recommended because the
SHOW RELAYLOG EVENTS command returns the complete contents of the relay log, which can be quite large.
This command does not return events related to setting user and system variables. If you need those, use mariadb-binlog/mysqlbinlog.
On the primary, this command does nothing.
If there is only one nameless primary, or the default primary (as specified by the default_master_connection system variable) is intended,
connection_name can be omitted. If provided, the
SHOW RELAYLOG statement will apply to the specified primary.
connection_name is case-insensitive.
MariaDB starting with 10.7.0
FOR CHANNEL keyword was added for MySQL compatibility. This is identical as
using the channel_name directly after
