Valkey

Key components like RDMA support and the CMake build system are labeled as experimental, meaning they may change or break in minor releases, limiting production readiness.

Building requires manual handling of dependencies (e.g., OpenSSL for TLS, RDMA libraries), and cached build options often necessitate a full `make distclean` to reset, adding setup overhead.

As a newer fork, it lacks the extensive third-party tools, client libraries, and community resources that Redis has built over years, potentially increasing integration effort.

The README is only a quick start, with full details on valkey.io, which may not be as comprehensive or integrated as Redis's official documentation, leading to potential gaps.
