| Spec score · In-Memory Databases | 9.1 (#2) | 7.4 (#19) |
| Founded | 2010 | 2019 |
| Integrations | Aerospike Connect includes connectors for Elasticsearch, Spark, Kafka, JMS, Pulsar, Trino, and Event Stream Processing, with additional licensing noted for these connectors. | Because KeyDB is Redis-compatible, the maker says Redis client libraries can also be used with KeyDB. |
| Intended users | Aerospike describes Enterprise Edition as suited to mission-critical workloads and data pipelines, including machine learning and generative and agentic AI workloads. | The maker describes KeyDB as useful from small projects to workloads serving millions of users. |
| Purpose | Aerospike Database is a real-time database designed for millisecond latency and large-scale transaction processing, including document access and graph traversal. | KeyDB is an open source, in-memory database used as a database, cache, and message broker. |
| Replication | Cross-Datacenter Replication provides asynchronous active-active replication between clusters, while synchronous active-active supports strongly consistent global transactions. | KeyDB supports asynchronous multi-master replication across regions using a last-write-wins method. |
| Security | Enterprise Edition lists TLS transport encryption, access control lists, Vault integration, and FIPS 140-2 compliance; some security features require additional licensing. | KeyDB offers TLS support for client connections, replication links, and the cluster bus, and its security guidance recommends restricting access to trusted clients. |
| Support | Community Edition includes community support, while Enterprise Edition includes enterprise production support and hot patch availability. | Support is community-based and managed by the KeyDB team at Snap; the maker says paid support services are unavailable. |
