Owen O'Malley updated HIVE-4579: -------------------------------- Attachment: pushdown.pdf Here's a quick write up of the intent of the interface. > Create a SARG interface for RecordReaders > ----------------------------------------- > > Key: HIVE-4579 > URL: https://issues.apache.org/jira/browse/HIVE-4579 > Project: Hive > Issue Type: Improvement > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Attachments: pushdown.pdf > > > I think we should create a SARG (http://en.wikipedia.org/wiki/Sargable) > interface for RecordReaders. For a first pass, I'll create an API that uses > the value stored in hive.io.filter.expr.serialized. > The desire is to define an simpler interface that the direct AST expression > that is provided by hive.io.filter.expr.serialized so that the code to > evaluate expressions can be generalized instead of put inside a particular > RecordReader. -- This message is automatically generated by JIRA.
