What is the relationship between the Protobuf models in bigquery.storage.v1 and JSON models in bigquery.model ?. about java-bigquery

[damnMeddlingKid]

It looks like there is code to go from the json model to proto https://github.com/apache/beam/blob/2c59a748b91a0988e0b8e332f18bd9db072c3e95/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java#L768

I don't know if the reverse exists. The mapping of type definitions is not public so there isn't something that can be easily imported.

@Neenu1995 Transferring this issue to BigQuery since it's BigQuery specific.

Hi @damnMeddlingKid ,

Sorry for the late reply:

1. There are no helper methods to convert between the 2 format from java-bigquery and java-bigquerystorage. The one that you have found is from apache beam. We'll look into unifying the interface differences in java-bigquery and java-bigquerystorage in the future.
2. The models may not be in complete sync with each other as the 2 libraries can follow different release schedule. However, in general, they will be relatively in sync as they are both generated source.

As this question is a year old, I'm closing this issue. Feel free to open another issue if you have further questions.
