Aerospike vs Elasticsearch: 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 Elasticsearch? Open Source, Distributed, RESTful Search Engine. Elasticsearch is a distributed, RESTful search and analytics engine capable of storing data and searching it in near real time. Elasticsearch, Kibana, Beats and Logstash are the Elastic Stack (sometimes called the ELK Stack).
Aerospike and Elasticsearch are primarily classified as "In-Memory Databases" and "Search as a Service" tools respectively.
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, Elasticsearch provides the following key features:
- Distributed and Highly Available Search Engine.
- Multi Tenant with Multi Types.
- Various set of APIs including RESTful
"Ram and/or ssd persistence " is the primary reason why developers consider Aerospike over the competitors, whereas "Powerful api" was stated as the key factor in picking Elasticsearch.
Aerospike and Elasticsearch are both open source tools. Elasticsearch with 42.4K GitHub stars and 14.2K forks on GitHub appears to be more popular than Aerospike with 296 GitHub stars and 55 GitHub forks.
Uber Technologies, Instacart, and Slack are some of the popular companies that use Elasticsearch, whereas Aerospike is used by JustWatch, AppsFlyer, and Flyclops LLC. Elasticsearch has a broader approval, being mentioned in 2003 company stacks & 979 developers stacks; compared to Aerospike, which is listed in 30 company stacks and 9 developer stacks.
