> 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: h-4579.patch, HIVE-4579.D11409.1.patch,
> HIVE-4579.D11409.2.patch, HIVE-4579.D11409.3.patch, 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.
