Zenko uses Redis-Sentinel to provide a highly available in-memory database for processes in:

  • CRR (pause and retry feature)
  • CloudServer
  • Backbeat API

In general, Redis-Sentinel is useful for short-term database needs, such as for a quick or temporary job, or for sharing as a shared database between two or more services. Information stored in Redis can be written, accessed, rewritten, and destroyed faster and more easily than with a full-featured database.
