Deployment Modes - CefasDB Docs
Run CefasDB locally, in Docker, on Kubernetes, as one node, or as a replicated cluster.
Documentation excerpt
CefasDB can run in several topologies. The API is stable across them; the difference is durability, failure behavior, and operational complexity.
Run cefasdb directly on a developer machine. This is best for development and debugging because logs, flags, data files, and binaries are all local.
You are learning CefasDB. You are debugging a CLI or SDK workflow. You want a disposable local database.
Do not use it when a process or machine failure must be transparent.
