<a href="https://github.com/datasift/quitsies" rel="nofollow">https://github.com/datasift/quitsies</a><p>My team needed to quickly build a drop in replacement for Memcached that persisted to disk. We chose RocksDB as the storage engine, but also wanted to avoid rewriting our clients.<p>We therefore built Quitsies to wrap RocksDB, but with only a subset of the Memcached API since the two are not fully compatible.<p>It has its caveats, but maybe other teams will find this useful.
