> Key: PARQUET-323
> URL: https://issues.apache.org/jira/browse/PARQUET-323
> Project: Parquet
> Issue Type: Bug
> Components: parquet-format
> Reporter: Cheng Lian
> Assignee: Lars Volker
> Priority: Major
> Fix For: format-2.5.0
>
>
> 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.
