Subject [jira] Updated: (HBASE-880) Improve the current client API by creating new container classes
Date Wed, 01 Oct 2008 20:39:44 GMT

     [ https://issues.apache.org/jira/browse/HBASE-880?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-880:
------------------------

    Attachment: NewCilentAPIProposoal4.gif

Sketch of proposal derived from previous work that adds new class to encapsulate specification
of table area or 'range' the Get or Delete operation applies to.  Does not include HTable.
 HTable would have three new methods rather than two: get, delete, and put (Proposal suggests
that we treat puts and deletes against a row distinctly to avoid conflict and in the name
of simplification).

> 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.
