----------------------------
Assignee: bharath v (was: Vaibhav Aggarwal)
Labels: patch (was: )
Affects Version/s: (was: 0.7.0)
0.9.0
Status: Patch Available (was: Open)
This patch converts *non row-key* predicates into corresponding hbase filters
and adds them to scan objects to save network IO. Current trunk does filtering
after TableScan operator.Tested it by observing reduction in number of rows
processed by TableScanOperator.
> support range scans and non-key columns in HBase filter pushdown

> HIVE-1226 added support for WHERE rowkey=3. We would like to support WHERE
> rowkey BETWEEN 10 and 20, as well as predicates on non-rowkeys (plus
> conjunctions etc). Non-rowkey conditions can't be used to filter out entire
> ranges, but they can be used to push the per-row filter processing as far
> down as possible.
