Rui Wang updated BEAM-7150:
---------------------------
Description:
There might be nested AND cases:
a = b AND (c = d AND (e = f)).
Such cases should be flattened as a = b AND c = d AND e = f.
This is useful because after done so, we can easily build keys for join inputs:
each conjunction clause contributes a field of key (key is Row in SQL
equi-join) for join inputs.
