Garnet is a remote cache-store from Microsoft Research that offers strong performance (throughput and latency), scalability, storage, recovery, cluster sharding, key migration, and replication features. Garnet can work with existing Redis clients.
Lightweight, fast and reliable key/value storage engine based on Bitcask.
One database for user-user (follows), user-item (likes), and item-item (related items) interactions — precomputed at write time, served as simple lookups
Simply ACID* key-value database. At the medium or even low latency it tries to provide greater throughput without losing the ACID properties of the database. The database provides the ability to create record headers at own discretion and use them as transactions. The maximum size of stored data is limited by the size of the computer's RAM.
