---------------------------------
Summary: Trim TupleFilter after dictionary-based filter
optimization
Key: KYLIN-2823
URL: https://issues.apache.org/jira/browse/KYLIN-2823
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
with cube's dictionary, kylin will optimize filters like:
( a = 'value_in_dict' OR a = 'value_not_in_dict') => (a =
'value_in_dict' OR ConstantTupleFilter.FALSE)
we need to further trim the filter to (a = 'value_in_dict') to avoid too many
children after flatten filter step
