Duo Zhang commented on HBASE-15921:
-----------------------------------
https://github.com/Apache9/hbase/blob/asynclocator/hbase-client/src/main/java/org/apache/hadoop/hbase/client/async/ZKAsyncRegistry.java
The async zookeeper registry, based on curator.
As the current locateRegionInMeta uses reversed scan, I think we need to find a
slow but simple way to implement it first. Otherwise we need to implement
asynchronous scan even if we only want to implement a AsyncTable with only get
operation support...
Thanks.
> Add first AsyncTable impl and create TableImpl based on it

> First we create an AsyncTable interface with implementation without the Scan
> functionality. Those will land in a separate patch since they need a refactor
> of existing scans.
> Also added is a new TableImpl to replace HTable. It uses the AsyncTableImpl
> internally and should be a bit faster because it does jump through less hoops
> to do ProtoBuf transportation. This way we can run all existing tests on the
> AsyncTableImpl to guarantee its quality.
