Summary: Extend storage-api to expose FilterContext
Key: HIVE-22958
URL: https://issues.apache.org/jira/browse/HIVE-22958
Project: Hive
Issue Type: New Feature
Components: storage-api
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
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
