Julien Le Dem updated PARQUET-323:
----------------------------------
    Comment: was deleted

(was: I think we should deprecate it and discourage its use. For backward compatibility, it has to stay.
https://github.com/apache/parquet-format/blob/master/LogicalTypes.md doesn't even refer to it.

> As discussed in the mailing list, {{INT96}} is only used to represent nanosec timestamp in Impala for some historical reasons, and should be deprecated. Since nanosec precision is rarely a real requirement, one possible and simple solution would be replacing {{INT96}} with {{INT64 (TIMESTAMP_MILLIS)}} or {{INT64 (TIMESTAMP_MICROS)}}.
