------------------------------------------
Summary: Wrong calculation of replies count for queries with
partition pruning and enabled parallelism
Key: IGNITE-16629
URL: https://issues.apache.org/jira/browse/IGNITE-16629
Project: Ignite
Issue Type: Bug
Components: sql
Reporter: Yury Gerzhedovich
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.
