Hi Michal,
Given that:
- data fields has a random shape (pseudo-random sequence of characters)
- You have only 2 short entries
I would argue that JSON+gzip will do any optimization. My intuition I that it’s bigger in size than any binary format (eg msgpack). Moreover, the readability argument doesn’t make sense because it’s the same effort to unzip it as to deserialize (eg for msgpack or bson). So, if you want to optimize then probably you we should choose different format than JSON .
