ASF GitHub Bot updated SPARK-58300:
-----------------------------------
Labels: pull-request-available (was: )
> Add from_protobuf option to keep Timestamp/Duration as struct<seconds, nanos>
> -----------------------------------------------------------------------------
>
> Key: SPARK-58300
> URL: https://issues.apache.org/jira/browse/SPARK-58300
> Project: Spark
> Issue Type: Improvement
> Components: Protobuf
> Affects Versions: 4.3.0
> Reporter: Ben Hollis
> Priority: Minor
> Labels: pull-request-available
>
> `from_protobuf` always maps `google.protobuf.Timestamp` -> `TimestampType`
> and `google.protobuf.Duration` -> `DayTimeIntervalType`. This is Spark's
> well-known-type conversion and there is currently no way to turn it off.
> This adds a `from_protobuf` reader option
> `convert.timestamp.duration.to.native` (default `true`, preserving today's
> behavior). When set to `false`, both well-known types fall through to the
> generic message path and deserialize as their raw proto shape
> `struct<seconds: bigint, nanos: int>`.
> Motivation: a consumer whose downstream schema was defined against the
> \{seconds, nanos} struct representation (e.g. a table populated by a
> different decode path) and must stay stable, or that needs the exact
> seconds/nanos rather than a microsecond-truncated interval/timestamp.
