Subject [jira] Commented: (HBASE-880) Improve the current client API by creating new container classes
Date Thu, 02 Oct 2008 19:47:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12636442#action_12636442

stack commented on HBASE-880:
-----------------------------

No.  I was thinking about this wrong fixated on current HTable getScanners API.  If I adopt
your suggestion, the HTable API would change so column names would be specified in this new
Map of columns to Scopes.

One thought is that we should probably check for case where Map includes a Scope for a column
and for its enclosing family and throw an exception if a Client attempts such a specification?

> 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.
