Tim Armstrong updated IMPALA-874:
---------------------------------
Labels: hbase (was: )
> Planner enhancement for HBase rowkey lookup and range scan
> ----------------------------------------------------------
>
> Key: IMPALA-874
> URL: https://issues.apache.org/jira/browse/IMPALA-874
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 1.0.1
> Reporter: Alan Choi
> Priority: Minor
> Labels: hbase
>
> The enhancement should tackle the following issues:
> 1. Turning Compound Predicate into row key look up - OR and IN predicate
> doesn't work today.
> 2. Apply equivalence class analysis to HBase scan
> 3. When multiple range predicates are present, Impala should pick tightest
> one. Currently, Impala picks the first set.
