Aerospike vs Apache Ignite: 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; Apache Ignite: *An open-source distributed database, caching and processing platform *. It is a memory-centric distributed database, caching, and processing platform for transactional, analytical, and streaming workloads delivering in-memory speeds at petabyte scale.

Aerospike and Apache Ignite can be primarily classified as "In-Memory Databases" tools.

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, Apache Ignite provides the following key features:

• Memory-Centric Storage
• Distributed SQL
• Distributed Key-Value
