---------------------------------
Summary: The table plan of hybrid shuffle may introduce additional
blocking edges occasionally
Key: FLINK-33612
URL: https://issues.apache.org/jira/browse/FLINK-33612
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.19.0
Reporter: Yuxin Tan
To enhance the performance of hybrid shuffle, it is imperative to address the
inconsistency between hybrid shuffle mode and blocking shuffle mode in certain
query plans of TPC-DS (such as q88.sql, q14a.sql, q14b.sql, etc).
In hybrid shuffle mode, these plans introduce additional blocking shuffle edges
and result in increased shuffle times, potentially impacting overall
efficiency.
