For bidirectional replication, reverse replication tasks now wait until the forward task finishes full replication before collecting logs for the reverse incremental replication task.	Data Replication
04-01	Data Replication	Redis / PolarDB-X Replication Optimization	Optimized the Redis full replication write mechanism.
