The main purpose of this work is to show results of benchmarking some of the leading in-memory NoSQL databases with a tool named YCSB.
We selected three popular in-memory database management systems: Redis (standalone and in-cloud named Azure Redis Cache), Tarantool and CouchBase and one cache system Memcached. Memcached is not a database management system and does not have persistence. But we decided to take it, because it is also widely used as a fast storage system. Our “firing field” was a group of four virtual machines in Microsoft Azure Cloud. Virtual machines are located close to each other, meaning they are in one datacenter. This is necessary to reduce the impact of network overhead in latency measurements. Images of these VMs can be downloaded by links: one, two, three and four (login: nosql, password: qwerty). A pair of VMs named nosql-1 and nosql-2 is useful for benchmarking Tarantool and CouchBase and another pair of VMs named nosql-3 and nosql-4 is good for Redis, Azure Redis Cache and Memcached. Databases and tests are installed and configured on these images.
Our virtual machines were the basic A3 instances with 4 cores, 7 GB RAM and 120 GB disk size.
