Thanks Maryann. It worked.
I am currently working on cost modeling for phoenix queries independently. Do
you think that anyone at salesforce would be interested in this project? I am
developing the cost model for automating schema design.

> 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.
