FoundationDB vs Riak: What are the differences?
FoundationDB: Multi-model database with particularly strong fault tolerance, performance, and operational ease. FoundationDB is a NoSQL database with a shared nothing architecture. Designed around a "core" ordered key-value database, additional features and data models are supplied in layers. The key-value database, as well as all layers, supports full, cross-key and cross-server ACID transactions; Riak: A distributed, decentralized data storage system. Riak is a distributed database designed to deliver maximum data availability by distributing data across multiple servers. As long as your client can reach one Riak server, it should be able to write data. In most failure scenarios, the data you want to read should be available, although it may not be the most up-to-date version of that data.
FoundationDB and Riak belong to "Databases" category of the tech stack.
"ACID transactions" is the top reason why over 2 developers like FoundationDB, while over 9 developers mention "High Performance " as the leading cause for choosing Riak.
