Ferricstore.Raft.Backend (ferricstore v0.4.0)

Runtime write backend.

WARaft is the only supported production path. Runtime selection is fixed here so deploys and benchmarks cannot drift through config flags.

Summary

running()

Returns the backend used by the currently running default application.

selected()

waraft?()

@spec running() :: :waraft | :undefined

Returns the backend used by the currently running default application.

This is intentionally separate from selected/0: default-instance runtime routing must stay pinned to the backend that actually booted.
