slow performance - Hive

slow performance - Hive

New Contributor

I do have some select and merge queries getting executed in Hive and it's all very slow.

 

Any idea how to improve the performance?

 

I have already tried the following...

 

1) Vectorization
2) CLUSTRED BY
3) Compute stats
4) hive.execution.engine = tez
5) hive.exec.parallel
etc..

Any advise for me?
