Sensaphone Introduces ValuStor, a Memcached Alternative Made to Run with ScyllaDB

In this presentation, we share approaches to replacing RAM-only caching infrastructure while achieving high performance against a persistent datastore. Memcached has proven very popular, but it also requires its uses to sacrifice reliability, scalability, redundancy, availability, and security. To address these issues, Sensaphone implemented a memcached replacement called ValuStor, an easy-to-use key-value database client layer written in C++ that works well with ScyllaDB. ValuStor includes features like client-side write queues, multi-threading support, automatic adaptive consistency, and support for multiple data types (including JSON).
