> Key: HIVE-22959
> URL: https://issues.apache.org/jira/browse/HIVE-22959
> Project: Hive
> Issue Type: Sub-task
> Components: storage-api
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Major
>
> To enable row-level filtering at the ORC level ORC-577, or as an extension
> ProDecode MapJoin HIVE-22731 we need a common context class that will hold
> all the needed information for the filter.
> I propose this class to be part of the storage-api – similar to
> VectorizedRowBatch class and hold the information below:
> * A boolean variable showing if the filter is enabled
> * A int array storing the row Ids that are actually selected (passing the
> filter)
> * An int variable storing the the number or rows that passed the filter
>
