Here is the image of the entries present in the database for which, proto file needs to written.

For example: I need to write a generic map in proto file in such a way that all the entries in the "PROPERTY_CATEGORY" should be converted to proto.

You can either use an Any or a struct to accomplish this

1. map<string, google.protobuf.Any>

2. Struct https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/struct.proto#L51
