Project Reactor: From Zero to Hero

In this series of pages, I will discuss project reactor and reactive programming from basic concepts to reactor internal implementation details. This discussion is based on the official reference documentation, the java-doc, talks by maintainers of reactor e.g. at the spring I/O and other distributed material, and should summarise and connect all this information. It should complement the official reference documentation and java-doc. Although the name says "from zero to hero", basic knowledge about the library is advised to fully benefit from it.

As a short disclaimer, I am a professional software engineer with some years of experience in using reactor, but not a maintainer or creator of the library. Information and knowledge in this post are based on the official documentation and talks, but I cannot exclude misconceptions on my side.

There are several ways to clone a repository from github. Similar from other providers, such as bitbucket, gitlab, etc.

Just small note for me. Hope the slide will be opened.

API design
- Idmpotency
  - It should be safe to retry an RPC without knowing whether it was processed

Some of the Redis best practices content has moved

This content from this markdown file has moved a new, happier home where it can serve more people. Please check it out : https://docs.microsoft.com/azure/azure-cache-for-redis/cache-best-practices.

NOTE: Client specific guidance listed below is still valid and should still be considered. I will update this document once all content has been moved.
