Subject [jira] Commented: (HBASE-880) Improve the current client API by creating new container classes
Date Tue, 16 Sep 2008 18:22:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631492#action_12631492
] 

Jean-Daniel Cryans commented on HBASE-880:
------------------------------------------

bq. Constructors for RowGet should have multiple overloads so you can get a single column,
multiple columns, multiple versions, a single timestamp or a pair of timestamps indicating
a range.

I would keep the two methods get and getRow as a way to be more transition-friendly. This
means that I would create 2 subclasses to RowOperation. Looking at the code inside HRS, it
also make more sense.

> The current API does not scale very well. For each new feature, we have to add many methods
to take care of all the overloads. Also, the need to batch row operations (gets, inserts,
deletes) implies that we have to manage some "entities" like we are able to do with BatchUpdate
but not with the other operations. The RowLock should be an attribute of such an entity.
> The scope of this jira is only to replace current API with another feature-compatible
one, other methods will be added in other issues.
