improvement
Michal Nowakiewicz created ARROW-14182:
------------------------------------------
Summary: [C++][Compute] Hash Join performance improvement
Key: ARROW-14182
URL: https://issues.apache.org/jira/browse/ARROW-14182
Project: Apache Arrow
Issue Type: Improvement
Reporter: Michal Nowakiewicz
Assignee: Michal Nowakiewicz
Add micro-benchmarks for hash join exec node.
Write a new implementation of the interface HashJoinImpl making sure that it is efficient for all types of join. Current implementation, based on unordered map, trades performance for a simpler code and is likely not as fast as it could be.
