Subject [jira] [Updated] (HBASE-12684) Add new AsyncRpcClient
Date Sun, 25 Jan 2015 02:33:35 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12684?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-12684:
--------------------------
    Release Note: 
Retrofit a new, netty-based rpc transport on the client. This client is slightly slower if
little contention given the extra tier or so that netty adds and that we block on a Future
waiting on the call to finish.  This client opens the way for HBase having a native Async
API.

This client is on by default in master branch (2.0 hbase). It is off in branch-1.0 (hbase-1.1.x).
 To enable it, set "hbase.rpc.client.impl" to "org.apache.hadoop.hbase.ipc.AsyncRpcClient"

  was:Retrofit a new, netty-based rpc transport on the client.

> With the changes in HBASE-12597 it is possible to add new RpcClients. This issue is about
adding a new Async RpcClient which would enable HBase to do non blocking protobuf service
communication.
> Besides delivering a new AsyncRpcClient I would also like to ask the question what it
would take to replace the current RpcClient? This would enable to simplify async code in some
next issues.
