Any specific reason for not porting to PrestoSQL ? It is more widely used and preferred by cloud provider's like quoble, stardust, google

Well I work at Uber, and we use prestodb :) so no specific motivation for me to do charity work on prestosql stuff.

@Himanshu Rathore PrestoSql currently lacks aggregation pushdowns
and implementation almost certainly will be different from PrestoDb, as there is a huge difference in the architectural view on how it should be done.

Actually .. if someone is interested we can share a fork that Uber used off 217 that does aggregation pushdown: it is probably not going to be accepted by prestosql since we had to build a new pushdown framework into prestosql. This work was done pre-fork off release 217. But it will take some work to make it work with prestosql now but At least this approach is similar to prestosql’s pushdown IR thinking
