[jira] [Created] (PARQUET-323) INT96 should be marked as deprecated

Cheng Lian created PARQUET-323:
----------------------------------

             Summary: INT96 should be marked as deprecated
                 Key: PARQUET-323
                 URL: https://issues.apache.org/jira/browse/PARQUET-323
             Project: Parquet
          Issue Type: Bug
          Components: parquet-format
            Reporter: Cheng Lian


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)}}.
