/*
Detail description of the lost data in mysql two-phase commit issue by @Fanduzi:
When using semi-sync and setting rpl_semi_sync_master_wait_point=AFTER_SYNC,
if an INSERT statement is being committed but blocks due to an unmet ack count,
the data inserted by the transaction is not visible to ReadMigrationRangeValues,
so the copy of the existing data in the table does not include the new row inserted by the transaction.
However, the binlog event for the transaction is already written to the binlog,
so the addDMLEventsListener only captures the binlog event after the transaction,
and thus the transaction's binlog event is not captured, resulting in data loss.
If write a changelog into ghc table before ReadMigrationRangeValues, and the transaction commit blocks
because the ack is not met, then the changelog will not be able to write, so the ReadMigrationRangeValues
will not be run. When the changelog writes successfully, the ReadMigrationRangeValues will read the
newly inserted data, thus Avoiding data loss due to the above problem.
