RE: Questions about HBase replication

But even with replicationSink, replicationSource still need to use RPC to ship entries. So, the potential problem you said may still occur. Replication has its own handler, which is different from normal handlers. You can check it from code:) Jieshan.

RE: Questions about HBase replication

1. Why does HBase replication need replicationSink? I think replicationSource can do replicationSink's work as well. And if we don't use replicationSink, we just need one time I/O. ReplicationSink used to apply all HLog edits to peer cluster. If we remove ReplicationSink from current

WritableRpcEngine$Invoker caches UGI

RE: replication scopes in WAL

Yes, it is only used for indicating which KVs to replicate. See ReplicationSource#removeNonReplicableEdits. bq.If they indicate which KVs to replicate, wouldn't it be better to store bitmask or something like that? Sounds like a good idea. Regards, Jieshan -Original Message- From:

RE: Shared ThreadPoolExecutor in HTable by default.

Use shared ThreadPoolExecutor will not always good, e.g. when we do metaScan or something else, we don't expect any delay due to no available threads in this shared pool. But that would always be a good practice for application-level. It is individual opinion only:) Jieshan -Original
