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 throughout the documentation, and in MariaDB commands, although MariaDB 10.5 has begun the process of renaming. The documentation will follow over time. See MDEV-18777 to follow progress on this effort.

Syntax

SHOW RELAYLOG ['connection_name'] EVENTS
    [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]

Description

On replicas, this command shows the events in the relay log. If 'log_name' is not specified, the first relay log is shown.

Syntax for the LIMIT clause is the same as for SELECT ... LIMIT.

Using the 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.

Requires the REPLICATION SLAVE ADMIN privilege (>= MariaDB 10.5.2) or the REPLICATION SLAVE privilege (<= MariaDB 10.5.1).

connection_name

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.
