Seems incomplete without any mention of Microsoft Azure options like Cosmos DB, Blob and Table storage, Data Lake, etc.

Also CouchDB for integrated API serving via views (?) and extreme replication abilities.

Surprised to see Riak labeled as a "caching" DB, but well.. I'm not sure they are an option for anything anymore.

It is nowhere near complete. It also doesn't mention DynamoDB from AWS as a key/value store despite being very common in the serverless world.
