[jira] [Commented] (ACCUMULO-2178) ColumnFamilyRangeIterator

["Vikram Srivastava (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-2178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13890469#comment-13890469 ] 

Vikram Srivastava commented on ACCUMULO-2178:
---------------------------------------------

[~elserj] If we add ranges for both cf and cq to the new Filter, then the ColumnSliceFilter becomes a special case of the new Filter where cf_start and cf_end are both null. Does that sound correct?

> It would be extremely useful in situations where you would like to specify a range of rows to iterate and also a range of column families within that range of rows. The current API requires that you specify a start/end key for each row that you will be scanning in the range of column families.
> There would be a lot gained from the ability to first seek to the beginning column specified in the range of columns, return all keys/values inside of that range, and then seek to the beginning of the range for the following row when the ending column family in the current row has been reached.
