Re: Impala runtime filter not working as expected

Expert Contributor

Alex,

 

Thank you again.

 

Subquery approach has been recommended to our team as a long term solution.

However, for short-tem solution to avoid regression impact, using view with limited partitions has been selected.

 

If I remember correctly, in MySQL `table A` data can be limited by `ON Clause` before joining so that cadidates for join can be reduced.

 

Thank you for your valuable comment.
