----------------------------------------------
Summary: Generalize columnar filter pushdown to accommodate
dynamic prefixes
Key: ASTERIXDB-3229
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3229
Project: Apache AsterixDB
Issue Type: Improvement
Components: COMP - Compiler, RT - Runtime
Affects Versions: 0.9.9
Reporter: Wail Y. Alkowaileet
Assignee: Wail Y. Alkowaileet
Fix For: 0.9.9
In order to support dynamic prefixes, we should generalize the columnar filter
pushdown to work on external datasets' dynamic prefixes.
As in columnar filters, dynamic prefixes filters should also work with
arbitrary functions (e.g., lowercase(field) = "some_string")
