Command-Line Format --relay-log-info-file=file_name Deprecated 8.0.18 System Variable relay_log_info_file Scope Global Dynamic No SET_VAR  Hint Applies No Type File name Default Value relay-log.info behavior is likely to result; this behavior depends on the other options used, the order in which they are specified, and whether they are specified on the command line or in an option file. For more information about how MySQL handles server options, see Section 4.2.2, “Specifying Program Options” . Replication and Binary Logging Options and Variables • relay_log_info_file The use of this system variable is now deprecated. It was used to set the file name for the replica’s applier metadata repository if  relay_log_info_repository=FILE  was set. relay_log_info_file  and the use of the  relay_log_info_repository  system variable are deprecated because the use of a file for the applier metadata repository has been superseded by crash- safe tables. For information about the applier metadata repository, see Section 17.2.4.2, “Replication Metadata Repositories” . • relay_log_info_repository Command-Line Format --relay-log-info-repository=value Deprecated 8.0.23 System Variable relay_log_info_repository Scope Global Dynamic Yes SET_VAR  Hint Applies No Type String Default Value TABLE Valid Values FILE TABLE The  FILE  setting wrote the replica’s applier metadata repository to a file, which was named  relay- log.info  by default. The name could be changed using the  relay_log_info_file  system variable. With the default setting, the replica stores its applier metadata repository as an  InnoDB  table in the mysql  system database named  mysql.slave_relay_log_info . For more information on the applier metadata repository, see Section 17.2.4, “Relay Log and Replication Metadata Repositories” . The use of this system variable is now deprecated. The setting  TABLE  is the default, and is required when multiple replication channels are configured. The  TABLE  setting for the replica’s applier metadata repository is also required to make replication resilient to unexpected halts. See Section 17.4.2, “Handling an Unexpected Halt of a Replica”  for more information. The alternative setting  FILE  was previously deprecated. 3521
