-------------------------------------
Summary: Control scan fragment parallelism by its processing cost
Key: IMPALA-12091
URL: https://issues.apache.org/jira/browse/IMPALA-12091
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 4.2.0
Reporter: Riza Suminto
Assignee: Riza Suminto
Impala still rely on MT_DOP option to decide parallelism of scan fragment when
query runs with COMPUTE_PROCESSING_COST=1. Planner should decide scan
parallelism by its processing cost instead of fixed count dictated by MT_DOP.
