[jira] [Updated] (SPARK-32444) Infer filters from DPP
[ https://issues.apache.org/jira/browse/SPARK-32444?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuming Wang updated SPARK-32444:
--------------------------------
Description:
For [this test suite|https://github.com/apache/spark/blob/69be17bfc3845668fd8f5aed8026c04da4496677/sql/core/src/test/scala/org/apache/spark/sql/DynamicPartitionPruningSuite.scala#L1285-L1297].
Table {{fact_stats}} is partitioned by {{store_id}} and table {{code_stats}} is partitioned by {{store_id}}.
DPP add a new predicate: {{fact_stats.store_id IN dynamicpruning#2723}}.
We can infer {{code_stats.store_id IN dynamicpruning#2723}} base on [{{t1.store_id = t2.store_id}}|https://github.com/apache/spark/blob/69be17bfc3845668fd8f5aed8026c04da4496677/sql/core/src/test/scala/org/apache/spark/sql/DynamicPartitionPruningSuite.scala#L1294].
