Key-value databases give applications a way to store and retrieve values by key. Compared on clustering support, deployment model, persistence modes, and supported protocols, these options also differ in TTL and multi-region support, as well as maximum value size. Free-plan availability and paid-from pricing add cost context. Amazon DynamoDB, Riak KV, and RocksDB are among the databases shown, with Aerospike Database and etcd also included. Consider the storage behavior, scale, and deployment choices your application needs, then compare the published capabilities that matter for its workload.
