Phil Yang commented on HBASE-17274:
-----------------------------------
ReplicationThrottler is not designed for multi-thread cases. I think the most
easy way is to use Guava's RateLimiter(since 13.0) which is a thread-safe
throttler. But we can not upgrade Guava expect 2.0. So I am going to implement
a similar work in HBase project.
> Add a server level throttler for replication sources

> If we have many peers or some servers have many recovered queues, the total
> read size per second from WALs will be very high.
> So we should add a server level throttler to limit the total speed of reading
> WALs.
