    Description

      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).

      Several projects (Impala, Hive, Spark, ...) support INT96.
      We need a clear spec of the replacement and the path to deprecation.
