GTIDs replace the file-offset pairs previously required to determine points for starting, stopping, or resuming the flow of data between source and replica. When GTIDs are in use, all the information that the replica needs for synchronizing with ...

You can add another replica to an existing replication configuration without stopping the source server. To do this, you can set up the new replica by copying the data directory of an existing replica, and giving the new replica a different server ...
https://dev.mysql.com/doc/refman/8.4/en/replication-multi-source-provision-replica.html
If the sources in the multi-source replication topology have existing data, it can save time to provision the replica with the relevant data before starting replication. In a multi-source replication topology, cloning or copying of the data ...
https://dev.mysql.com/doc/refman/8.4/en/replication-privilege-checks.html
By default, MySQL replication (including Group Replication) does not carry out privilege checks when transactions that were already accepted by another server are applied on a replica or group member. You can create a user account with the ...
MySQL 8.4 Reference Manual :: 19.2.1.3 Determination of Safe and Unsafe Statements in Binary Logging
https://dev.mysql.com/doc/refman/8.4/en/replication-rbr-safe-unsafe.html
The “safeness” of a statement in MySQL replication refers to whether the statement and its effects can be replicated correctly using statement-based format. If this is true of the statement, we refer to the statement as safe; otherwise, we ...
https://dev.mysql.com/doc/refman/8.4/en/replication-rbr-usage.html
MySQL uses statement-based logging (SBL), row-based logging (RBL) or mixed-format logging. The type of binary log used impacts the size and efficiency of logging. Therefore the choice between row-based replication (RBR) or statement-based ...
https://dev.mysql.com/doc/refman/8.4/en/replication-rules-channel-based-filters.html
This section explains how to work with replication filters when multiple replication channels exist, for example in a multi-source replication topology. Replication filters can be global or specific to a channel, enabling you to configure ...
https://dev.mysql.com/doc/refman/8.4/en/replication-snapshot-method.html
If the source database contains existing data it is necessary to copy this data to each replica. There are different ways to dump the data from the source database. To select the appropriate method of dumping the database, choose between these ...
https://dev.mysql.com/doc/refman/8.4/en/replication-solutions-performance.html
As the number of replicas connecting to a source increases, the load, although minimal, also increases, as each replica uses a client connection to the source. Also, as each replica must receive a full copy of the source's binary log, the network ...
