> Key: HIVE-20730
> URL: https://issues.apache.org/jira/browse/HIVE-20730
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 4.0.0
> Reporter: Eugene Koifman
> Assignee: Saurabh Seth
> Priority: Major
>
> since HIVE-16812 {{VectorizedOrcAcidRowBatchReader}} filters delete events based on min/max ROW__ID in the split which relies on {{hive.acid.index}} to be in the ORC footer.
> There is no way to generate {{hive.acid.index}} from a plain query as in HIVE-20699 and so we need to make sure that we generate a SARG into delete_delta/bucket_x based on stripe stats even the index is missing
