Re: Add support for repeated columns in the filter2 API [PARQUET-34]

[Flavio Pompermaier]

Hi Ryan,
second question: actually I need more  the 'in' wrt 'contains' (contains
for me means to check wheter ONE element is contained in a list, while 'in'
could be expressed also as a sequence of OR'ed contains).
Thus, I don't know which operator is better to implement first, in terms of
performance and implementation complexity. What do you suggest?
