> Currently a simple query is freezing forever if query parallelism is enabled and partition pruning extracts more than one partition. This caused by wrong replies count estimation made on a reducer node.
> The problematic query looks like this: {{{}select * from t where aff_key in ('a', 'b', 'c'){}}}.
> Please note that field _aff_key_ should be an affinity key and be a part of the compound PK.
