Aerospike vs. Redis comparison
See key differences between the two solutions at a glance.
| Redis | Aerospike | |
|---|---|---|
| Architecture | Single instance, single-threaded in-memory data structure store; limited support for multi-threading | Natively distributed, multi-threaded noSQL database |
| Data models | Key-value plus document, time-series, vector | Multi-model (key-value, document, graph) |
| Caching | Flexible caching in the cloud or on-prem | Easily configured as a high-speed cache (in-memory only) |
| Clustering | Single instances connected via Redis cluster proxy; requires separate child processes to act as a distributed database | Designed from the outset as a distributed database with automatic load balancing to ensure single hop to data |
| Storage model | In-memory, optional persist to file system | Custom, high-performance format with storage engine choice |
| Client access | Relies on a proxy model for clustering to reroute client requests to the appropriate node | Smart Client™ directly routes requests to the appropriate node to minimize network hops and enhance performance |
| Scalability options | Horizontal scaling is the only option, and it disruptively reshuffles most of the data | Vertical and horizontal scaling. Automatic data movement and automatic rebalancing when adding nodes |
| Consistency | High Availability (AP) mode and support for eventual consistency | Both High Availability (AP) mode and Strong Consistency (CP) mode to support varying use cases |
| Fault tolerance | High availability managed with Redis Sentinel or Redis Cluster | Two replicas for High Availability. Automated failovers. |
| Multi-site support | Primary-replica architecture | Automated data replication across multiple clusters; A single cluster can span multiple sites |
| Interoperability | A range of ready-made connectors available from third parties | Wide range of ready-made connectors available from Aerospike |
| Persistence options | Persistence is optional via snapshots or append-only files (AOFs). It can optionally be persisted by another database (e.g., RocksDB or Speedb) | Persist to SSD by default, non-persistence for in-memory/caching user cases, and a combination of SSD and memory persistence |
| Change data capture (CDC) | CDC offered through additional Redis Data Integration (RDI) product | Integrated CDC via change notifications with granular data options and automated batch shipments to maximize efficiency |
| Multi-tenancy | Either via multi-instance deployment, containerization, or software multi-tenancy | Various Aerospike server features enable effective multi-tenancy implementations |
| Hardware optimization | Designed for commodity servers | Designed to exploit modern hardware and networking technologies to maximize performance |
