MySQL Error 4016: GTID Replication Skip Counter Mismatch
Description
Error 4016 indicates that the `sql_slave_skip_counter` variable is being used on a replication channel where its effect is nullified by the `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS` setting. This typically occurs in GTID-based replication environments when attempting to skip transactions using a counter on a channel configured not to assign GTIDs to anonymous transactions. The error signals that the intended skip operation will not be performed.
Error Message
The value of sql_slave_skip_counter will only take effect for channels running with ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS <> OFF.
Known Causes
3 known causesIncompatible GTID Channel Configuration
The replication channel is configured with `ASSIGN_GTIDS_TO_ANONYMOUS_TRANSACTIONS = OFF` (or equivalent), making `sql_slave_skip_counter` ineffective for that channel.
Misunderstanding of GTID Replication Behavior
Attempting to use `sql_slave_skip_counter` in a GTID-enabled environment without fully understanding its limited applicability and interaction with GTID assignment settings.
Manual Replication Recovery Attempt
The error often arises during manual intervention or recovery efforts where `sql_slave_skip_counter` is set to bypass problematic transactions without considering the channel's GTID configuration.
