MySQL 8.0 Reference Manual  /  ...  /  Replication Channel Naming Conventions

17.2.3.4 Replication Channel Naming Conventions

This section describes how naming conventions are impacted by replication channels.

Each replication channel has a unique name which is a string with a maximum length of 64 characters and is case insensitive. Because channel names are used in slave tables, the character set used for these is always UTF-8. Although you are generally free to use any name for channels, the following names are reserved:

  • group_replication_applier

  • group_replication_recovery

The name you choose for a replication channel also influences the file names used by a multi-source replication slave. The relay log files and index files for each channel are named relay_log_basename-channel.xxxxxx, where relay_log_basename is a base name specified using the --relay-log option, and channel is the name of the channel logged to this file. If you do not specify the --relay-log option, a default file name is used that also includes the name of the channel.
