Aerospike vs Couchbase: What are the differences?
What is Aerospike? Flash-optimized in-memory open source NoSQL database. Aerospike is an open-source, modern database built from the ground up to push the limits of flash storage, processors and networks. It was designed to operate with predictable low latency at high throughput with uncompromising reliability – both high availability and ACID guarantees.
What is Couchbase? Document-Oriented NoSQL Database. Developed as an alternative to traditionally inflexible SQL databases, the Couchbase NoSQL database is built on an open source foundation and architected to help developers solve real-world problems and meet high scalability demands.
Aerospike belongs to "In-Memory Databases" category of the tech stack, while Couchbase can be primarily classified under "Databases".
Some of the features offered by Aerospike are:
- 99% of reads/writes complete in under 1 millisecond.
- Predictable low latency at high throughput – second to none. Read the YCSB Benchmark.
- The secret sauce? A thousand things done right. Server code in ‘C’ (not Java or Erlang) precisely tuned to avoid context switching and memory copies. Highly parallelized multi-threaded, multi-core, multi-cpu, multi-SSD execution.
On the other hand, Couchbase provides the following key features:
- JSON document database
- N1QL (SQL-like query language)
- Secondary Indexing
"Ram and/or ssd persistence " is the top reason why over 9 developers like Aerospike, while over 13 developers mention "Flexible data model, easy scalability, extremely fast" as the leading cause for choosing Couchbase.
