[summary] this paper explores in depth how the core features of the message medium are achieved in parallel with high-yielding, high-availability designs. In producer design, coverage covers information construction, serialization, routing strategies and reliability assurance (e. G. Ack mechanisms). Consumers partially analysed the extraction/pushing patterns, zoning distribution and information confirmation mechanisms. At the same time, broker, as a core component, is responsible for the routing, storage and delivery of messages and for rapid retrieval through indexing techniques. High-symmetric design focused on document storage (sequenced writing, sub-storage), log structure storage and load balancing strategies (e. G. Hashi division, queries division). To make sure you can
