> Allow Parquet to Proto conversion even though Target Schema has less fields
> ---------------------------------------------------------------------------
>
> Key: PARQUET-2305
> URL: https://issues.apache.org/jira/browse/PARQUET-2305
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-protobuf
> Reporter: Sanjay Sharma
> Priority: Major
>
> If Parquet has any field which has been removed from the schema and Parquet
> to Proto conversion happens, it errors out due to Unknown fields. There could
> be some scenarios that we want to still convert PARQUET into the target proto
> schema object which has lesser fields.
> If specified "ignoreUnknownFields" as an argument, this should allow the
> conversion which ignore fields it can't convert and not error out.
> Similar functionality exist in
> [https://github.com/protocolbuffers/protobuf/blob/main/java/util/src/main/java/com/google/protobuf/util/JsonFormat.java]
> with field "ignoringUnknownFields"
