Subject [jira] Updated: (HBASE-880) Improve the current client API by creating new container classes
Date Tue, 02 Dec 2008 07:05:44 GMT

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

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

    Attachment: 880.patch

Some progress.  Made RowOperations comparable so can see if they are of same Row.  Can't use
RowResult because need a Map of column to 'Cells' rather than column to 'Cell' as is RowResult
so we can return multiple versions of a cell in the one fetch.  Prune Iterable from Cell (internally
could do more than one version of itself -- a weird facility we no longer need it seems).

> 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.
