----------------------------------
Summary: where clause optimization in join queries work not well
Key: PHOENIX-3310
URL: https://issues.apache.org/jira/browse/PHOENIX-3310
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.8.0
Reporter: wangweiyi
select * from xxx x join yyy y on x.col1=y.col1 where x.col1='1'
select * from xxx x join yyy y on x.col1=y.col1 where y.col1='1'
the column "col1" is the primary key for table "xxx" and table "yyy"
the above SQL do full scan over either table "xxx" or "yyy". if the join
compiler take the where clause into account, this can be optimized.
