------------------------------------
Summary: Make filters work with nullable attributes and open types
Key: ASTERIXDB-1966
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1966
Project: Apache AsterixDB
Issue Type: Improvement
Components: STO - Storage
Reporter: Ian Maxon
Priority: Minor
It would be nice if filters worked on nullable attributes and open types. Right
now we disallow this because the implementation in the storage as it stands
expects the attribute to be present all the time. Given that indexes can deal
with this case however it is a bit odd. Open types should be fairly simple, but
for the case when the attribute is not present, we have to be careful to
basically "open" the filter entirely for that LSM component which contains the
tuple missing a filter value, as to not occlude it from searches.
