Review Comment:
The reason of priority set to LPC_REPLICATION_LONG_LOW is to reduce the
impact of duplication on normal read/write operations on the master cluster.
There are some usage scenarios of the duplication, some user cares about the
latency, some cares about the master cluster's thoughput.
How about add a configuration for it?
