-------------------------------------
Summary: Flexible join optimization based on partition transform
specs
Key: HIVE-28414
URL: https://issues.apache.org/jira/browse/HIVE-28414
Project: Hive
Issue Type: Sub-task
Components: Iceberg integration, StorageHandler
Reporter: Shohei Okumiya
This ticket would try to introduce as flexible join optimization as Apache
Spark.
Apache Spark can optimize a join algorithm when joining keys on both tables
share compatible partition specs. For example, both tables have `PARTITION
SPEC(day(ts))` and a statement has `FROM a JOIN b ON a.ts = b.ts`, Spark can
optimize the join.
