---------------------------------
Fix Version/s: connect-rust-4.3.0
> Parse the interval ranges, name:type fields and type spellings of
> DataType.fromDDL as the server does
> -----------------------------------------------------------------------------------------------------
>
> Key: SPARK-61308
> URL: https://issues.apache.org/jira/browse/SPARK-61308
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: Hyukjin Kwon
> Priority: Major
> Fix For: connect-rust-4.3.0
>
>
> DataType.fromDDL in the Rust client turns invalid interval strings into a
> wrong type or into CalendarInterval, and rejects the name:type field form
> without a space and several Spark DDL spellings. Repro:
> DataType.fromDDL("interval year to second") returns CalendarInterval and
> DataType.fromDDL("interval hour to day") returns a reversed DayTimeInterval
> range, while the server raises ParseException for both.
> DataType.fromDDL("a:int") fails with INVALID_DATATYPE_FORMAT, while the
> server returns struct<a:int>.
> Spellings the server accepts and the client rejects: a bare decimal,
> decimal(p), dec, numeric, real, character(n), timestamp_ltz, timestamp
> without time zone, timestamp with local time zone and time without time zone.
