Key Takeaways

  1. Redis is an open-source, in-memory data structure store that can be used as a database, cache, and message broker.
  2. Aerospike is a high-performance, distributed, in-memory NoSQL database.
  3. Redis is better suited for small to medium-scale applications than Aerospike for large-scale applications.

Redis vs Aerospike

The difference between Redis and Aerospike is that Redis is an in-memory data structure store, whereas Aerospike is a flash-optimized in-memory database. Redis has a password-based architecture, and Aerospike requires roles and access rights. Aerospike is designed to be used with large datasets, and Redis is perfect for small data storage.

Redis, developed by Salvatore Sanfilippo, stands for remote dictionary server. It is an in-memory, fast, open-source, NoSQL database that is used for databases, cache, and message broker purposes.

Aerospike, developed by Aerospike, is a flash-optimized, in-memory, open-source, key-value NoSQL database. It supports a vast range of data schemas and has the ACID property.

What is Redis?

Redis, as discussed above, has a BSD licensed in-memory NoSQL database, which is very fast and used as a database, cache and message broker, and queue.

Due to the high resemblance of its data structures with the programming language native data structures, which the programmers use inside applications, it is easy to use.

Redis has a Master-Slave architecture, and thus, the server can be run in two modes one is the Master mode, and the other is the Slave mode.

The user can configure in which mode they want to read and write from. In the new version of Redis, which is Redis 5.0, a new data structure has been introduced that is Streams alongside a new set of commands for sorted sets and new capabilities for Module APIs.

What is Aerospike?

Aerospike, as discussed above, is a flash-optimized, in-memory, open-source, key-value NoSQL database that was released in the year 2012 and developed by Aerospace.

The client layer consists of the open-source client libraries that are used to track cluster configuration, and it also manages the communication system between the client and the cluster nodes.

Lastly comes the third layer, which is the data storage layer. This layer manages the storage of data in SSD and Flash. It is designed for the purpose of storing large datasets as it is persistent and fast.

Main Differences Between Redis and Aerospike

  1. Redis was originally developed by Salvatore Sanfilippo while he was trying to enhance his Italian startup, whereas Aerospike was developed by Aerospike.
  2. Redis has a master-slave-based architecture which means that it can be run in two modes, master mode, and slave mode.
