Jim Kellerman updated HBASE-33:
-------------------------------
Priority: Critical (was: Blocker)
> Add a HTable get/obtainScanner method that retrieves all versions of a
> particular column and row between two timestamps
> -----------------------------------------------------------------------------------------------------------------------
>
> Key: HBASE-33
> URL: https://issues.apache.org/jira/browse/HBASE-33
> Project: Hadoop HBase
> Issue Type: Sub-task
> Components: client
> Reporter: Peter Dolan
> Assignee: Jim Kellerman
> Priority: Critical
> Fix For: 0.19.0
>
>
> The use case:
> * A weblog application for which rows are user ids and posts are stored in a
> single column, with post date specified by the cell's timestamp. The
> application would then need to be able to display all posts for the last week
> or month.
> * A feedfetcher for which rows are URLs and feed posts are stored in a single
> column with the post publish date or fetch time stored in the cell's
> timestamp. The application would then need to be able to display all posts
> for the last week or month.
> Proposed API:
> // Get all versions of the specified row and column whose timestamps are in
> [minTimestamp, maxTimestamp]
> SortedMap<long, byte[]> getTimestamps(Text row, Text column, long
> minTimestamp, long maxTimestamp);
> // Get all versions of the specified row and column whose timestamps are >=
> minTimestamp
> SortedMap<long, byte[]> getTimestamps(Text row, Text column, long
> minTimestamp);
> I'd be happy to take this on myself, as I need it for the above use cases
> before migrating my application over to HBase.
