Aerospike vs Redis: What are the differences?


In this article, we will discuss the key differences between Aerospike and Redis. Both Aerospike and Redis are highly popular databases used for different purposes. Understanding their differences will help in choosing the most suitable option for specific use cases.

  1. Data Structure: Aerospike is a key-value store that supports the storage of complex serialized data structures, such as lists and maps, within a single value. On the other hand, Redis is an in-memory data structure store that supports various data structures, including strings, hashes, sets, lists, and more.

  2. Data Persistence: Aerospike supports both in-memory and durable storage options. It can persist data on disk and provide high availability even in the event of a node failure. Redis primarily focuses on in-memory storage but provides the ability to persist data to disk asynchronously or synchronously using different persistence options.

  3. Scalability: Aerospike is designed to scale horizontally and can distribute data across multiple nodes in a cluster seamlessly. Redis, on the other hand, was initially designed to be a single-threaded, in-memory database, but can also be clustered to achieve scalability by sharding data across multiple nodes.

  4. Performance: Aerospike is built with performance and low-latency in mind and is able to handle high throughput workloads efficiently. Redis is also known for its high performance and low latency, especially for read-heavy workloads, due to keeping the data in memory.

  5. Replication: Aerospike uses a strong consistency model for replication, ensuring that data is replicated synchronously across multiple nodes. Redis supports both asynchronous and synchronous replication, allowing flexibility in choosing the replication strategy based on specific use cases.

  6. Advanced Data Types: Redis offers a rich set of advanced data types and operations on those types, such as sorted sets, hyperloglogs, and bitmap operations. Aerospike, while also supporting complex data structures, does not have as extensive support for advanced data types as Redis.

In summary, Aerospike and Redis differ in terms of their supported data structure, data persistence options, scalability, performance, replication strategy, and support for advanced data types. Understanding these differences will help in choosing the appropriate database for specific use cases.
