NoSQL databases power some of the biggest sites. They're fast and super scalable but how do they work? Behind-the-scenes, they use a keyspace to distribute your data across multiple servers or partitions. This allows them to scale horizontally across many thousand servers. NoSQL databases can operate in multiple modes: as key-value store, document store or wide column store. You can run your own NoSQL database with software like Cassandra, CouchDB, MongoDB or Scylla. You can also use a cloud version like AWS DynamoDB, Google Cloud BigTable or Azure CosmosDB. 💌 Sign up for Simply Explained Newsletter: Monthly newsletter with cool stuff I found on the internet (related to science, technology, biology, and other nerdy things)!
