> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Frontend
> Affects Versions: Impala 4.0

> Currently MAX_CNF_EXPRS is set to unlimited by default, with a complex querie
> that container many predicates the CNF rewrite can lead to significant
> frontend memory usage and eventually OutOfMemory. A potential default value
> could be in the range of 1000, but it should work well with the current
> TCP-DS queries.
