An introduction to MessagePack library for converting objects to more efficient binary format than JSON. Reports users saving up to 50% storage space, and in Redis RPC use case, MessagePack reduces both database storage requirements and transfer times during sudden request spikes by making messages smaller and faster to transmit.

Explores Remote Procedure Call as pattern for microservices architecture, comparing to message queues. Demonstrates JSON-RPC for message formatting with Redis pub/sub system for message distribution, showing how client waits for RPC return results while message queues typically trigger jobs without reply requirements.
