Owen O'Malley created HIVE-4579: ----------------------------------- Summary: 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
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.
