Subject [jira] [Commented] (HBASE-17372) Make AsyncTable thread safe
Date Tue, 27 Dec 2016 09:48:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15780055#comment-15780055

Duo Zhang commented on HBASE-17372:
-----------------------------------

For now the read timeout is for exists, scan and get, and write timeout is for all other operations.
For batch, if a group only have Get then we use read timeout, if no Get then we use write
timeout, if both then we will use the larger one.

Agree that we'd better use a single rpc timeout as the user may not set the correct timeout,
for example, set read timeout but calling checkAndPut. Then how do we deal with the default
rpc timeout of batch? A new timeout config for batch? Then should multiGet, multiPut use the
batch timeout?

Yeah maybe we do not need to introduce so many rpc timeout configs as it could be changed
per call now...

> The most methods are already thread safe. The problem is that we have some methods that
used to set timeout, we need to remove these methods and add a parameter for each call to
specific timeout settings.
