MessagePack

The MessagePack or MsgPack is a type of serializer for binary information, but, as the official tool's own website says, "It's like JSON, but fast and small."

The proposed MsgPack is serializing data quickly and with reduced size, thus offering a more efficient package for communication between microservices. At first, the MsgPack was not more efficient than the other serializers, but this problem has been overcome with this change.

When it comes to compatibility between the programming languages, MsgPack is very good; it just has a library of the most well-known languages of the market. The offer goes from Python libraries to Racket, for example.

The MsgPack does not have a native tool in the shipping package; it is left to the developer. This can be a problem because a layer of communication between microservices that supports multilingual stacks still needs to be found.
