How does Key Value Databases work?

FAQ about Key Value Databases?
Can key value databases handle complex queries?
No, they only support retrieval by exact keys, not complex queries.
Are key value stores persistent?
Many support persistence but some are in-memory only, depends on the tool.
Is data stored in key value DBs structured?
Nope, values are usually blobs or serialized objects, the DB doesn’t understand their structure.
Can I use key value DBs for user sessions?
Yes, they’re often used for session state because of fast access.
How do key value DBs scale?
They scale well by sharding data across multiple nodes keyed by the key.
