John Henton commented on HADOOP-2554:
-------------------------------------
Is it possible to have the row and column parameters accept regex as well? For
instance, inline with the user scenario above, I need to get all of the feed
posts from pages within the domain "org\.apache\..*". And I'd also like to
request the cells from a column family and not be restricted to a single column.
> Add a HTable get method that retrieves all versions of a particular column
> and row between two timestamps

> Key: HADOOP-2554
> URL: https://issues.apache.org/jira/browse/HADOOP-2554
> Project: Hadoop
> Issue Type: New Feature
> Components: contrib/hbase
> Reporter: Peter Dolan
> Priority: Minor
>
> 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.
