Subject Spark version performance
Date Wed, 12 Dec 2018 01:57:24 GMT

I'm having a little performance issue, with different Spark versions.

to 2.3.2 , with no any code changes It becomes slower.

apply transformations with filters and performs aggregation over it. It's
source is mainly parquet and no write is done just a serialization from the

Maybe I'm using  deprecated api functions or the order of the operations
are not generating a good plan...

Can someone give me some idea of any change on the versions that could
generate this behavior?
