Reactive serialization & deserialization [SPR-14156]

[spring-projects-issues]

Rossen Stoyanchev opened SPR-14156 and commented

Provide Decoder for decoding a byte stream to higher-level objects and Encoder for encoding objects into a byte stream. This is similar to existing converter mechanisms (e.g. HttpMessageConverter) but built for use with Reactive Streams.

The new Encoder and Decoder should simply work with Reactive Streams and the new DataBuffer abstraction (see #18727) and therefore be reusable in different context (Web, JMS, etc).

Given the choice to use Project Reactor for Reactive Streams support internally, input can be exposed as a Reactor Flux while output can be provided as a plain Reactive Streams Publisher which could be Flux or any Reactive Streams Publisher.
