----------------------------------------
Summary: Predicate pushdown API (BaseRelation) to push down OR
operators
Key: ACCUMULO-3494
URL: https://issues.apache.org/jira/browse/ACCUMULO-3494
Project: Accumulo
Issue Type: Improvement
Reporter: Corey J. Nolet
Currently, the BaseRelation API allows a FilteredRelation to handle an
Array[Filter] which represents a bunch of filter operations that are applied as
an AND- that is, the set returned should be the intersection of all of the
given filters.
It would be very much useful if OR operations could be applied in a
BaseRelation as well. I'm not sure what this would look like in terms of API
changes, but it almost seems like a FilteredUnionedScan BaseRelation (the name
stinks but you get the idea) would be useful.
