RSocket is an application protocol initially developed by Netflix, that supports Reactive Streams. The motivation behind its development was to replace hypertext transfer protocol (HTTP), which is inefficient for many tasks such as microservices communication, with a protocol that has less overhead.
It enables the following symmetric interaction models via async message passing over a single connection:
- request/response (stream of 1)
- request/stream (finite stream of many)
- fire-and-forget (no response)
- channel (bi-directional streams)
