Hi Giorgio, If just IDL (Interface description language), then we still implement these interfaces using different languages.
I do not think protobuf works. It can describe the format of TsFile, but using protobuf to serialize data maybe not a good idea, as we then are hard to know the meaning of each byte. Besides, I am not sure protobuf can provide the best compression. e.g., the first 12 bytes are magic string + version. If using protobuf, how to constrain that? Maybe many fields will have to be defined as bytes (define them as string will waste space as we know the length of the string). But maybe we can do some experiments.
