-----------------------------------
Summary: Fuse Selection in BuildHash
Key: QUICKSTEP-96
URL: https://issues.apache.org/jira/browse/QUICKSTEP-96
Project: Apache Quickstep
Issue Type: Improvement
Components: Query Optimizer, Relational Operators
Reporter: Zuyu Zhang
We may improve the hash join performance by avoiding intermediate
materialization for a table scan on the stored build relation with predicates,
if the SelectOperator is not used as repartition.
To this end, we may add an optimization rule on the physical plan, and we need
to make sure it works with FilterJoin as well.
