Aerospike vs Hazelcast: What are the differences?
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; Hazelcast: Clustering and highly scalable data distribution platform for Java. With its various distributed data structures, distributed caching capabilities, elastic nature, memcache support, integration with Spring and Hibernate and more importantly with so many happy users, Hazelcast is feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.
Aerospike and Hazelcast belong to "In-Memory Databases" category of the tech stack.
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, Hazelcast provides the following key features:
- Distributed implementations of java.util.{Queue, Set, List, Map}
- Distributed implementation of java.util.concurrent.locks.Lock
- Distributed implementation of java.util.concurrent.ExecutorService
"Ram and/or ssd persistence " is the top reason why over 9 developers like Aerospike, while over 4 developers mention "High Availibility" as the leading cause for choosing Hazelcast.
