                 Key: FLINK-35530
                 URL: https://issues.apache.org/jira/browse/FLINK-35530

Add a protobuf option that allows calling _CodedStreamHelper.discardUnknownFields_ to save the performance overhead of deserializing unknown fields when decoding data.
{code:java}
create table source (...) with (
 'format' = 'protobuf',
 'protobuf.discard-unknown-field' = 'true'
){code}
