             Summary: Join Query optimization
                 Key: PHOENIX-16
                 URL: https://issues.apache.org/jira/browse/PHOENIX-16
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: abhishek


select * from t1 inner join t2 on t1.col1 = t2.col2 where t1.id < 1000 and t2.id < 1000

For above query, phoenix first join the tables t1 and t2, and then apply the filter t1.id
< 1000 and t2.id < 1000. This is very inefficient. This can be easily fixed by pushing
the filter operation before the join query.
