> 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.
