| Consistency | Aerospike offers high-availability consistency and strong consistency with distributed ACID transactions. | Timestamp-based version control resolves conflicts by returning the most recent value. |
| Replication | Cross-Datacenter Replication provides asynchronous active-active replication between clusters, while synchronous active-active supports strongly consistent global transactions. | Nodes write operations to journals and replicas synchronize missing journal entries from their primary. |
| Security | Enterprise Edition lists TLS transport encryption, access control lists, Vault integration, and FIPS 140-2 compliance; some security features require additional licensing. | The documentation describes username and password client authentication, shared keys for node communication, and optional TLS. |
| Support | Community Edition includes community support, while Enterprise Edition includes enterprise production support and hot patch availability. | The repository invites users to join its Discord server to talk with maintainers and other users. |

SuperMassive
SuperMassive is a self-hosted, open-source key-value database built for in-memory work, durability, and low latency. It spreads data across shards, and additional nodes can expand capacity horizontally. Writes rotate among primary nodes in sequence; reads run in parallel across primaries and, when needed, replicas. The project describes automatic failover and recovery when a node fails. Timestamp-based versioning settles conflicts in favor of the latest value. Commands include PUT, GET, DEL, INCR, DECR, REGX, STAT, RCNF, and PING. Nodes journal operations, while replicas copy any missing journal entries from their primary. Client connections use username-and-password authentication; nodes can use shared keys, and TLS is optional. Linux, macOS, and Windows builds are available as binaries or source, under the BSD-3-Clause license. The README identifies two limits: no transactions and only one user. GitHub marks the repository archived and read-only as of May 6, 2026.
