Asif updated SPARK-45926:
-------------------------
Affects Version/s: 4.0.0
> The InMemoryV2FilterBatchScan and InMemoryBatchScan are not implementing
> equals and hashCode correctly
> -------------------------------------------------------------------------------------------------------
>
> Key: SPARK-45926
> URL: https://issues.apache.org/jira/browse/SPARK-45926
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.0.0, 3.5.1
> Reporter: Asif
> Priority: Major
> Labels: pull-request-available
>
> These InMemoryV2FilterBatchScan and InMemoryBatchScan test classes are not
> implementing hashCode and equals correctly as they are not taking into
> account the pushed runtime filters. As a result they are unable to expose the
> TPCDS test issues which can show whether the reuse of exchange is happening
> correctly or not.
> If these classes implement equals and hashCode taking into account the pushed
> runtime filters, we would see that TPCDS Q14b which should ideally be
> reusing the exchange containing Union , is not happening due to multiple
> bugs which surface in AQE.
> Actual V2 DataSources like iceberg correctly implement equals and hashCode
> taking into account pushed runtime filters , which also expose the same issue
> of reuse of exchnage not happening
