Namespaces in Redis?

Question

Is it possible to create namespaces in Redis?

From what I found, all the global commands (count, delete all) work on all the objects. Is there a way to create sub-spaces

Answer 1

If you are using Node, ioredis has transparent key prefixing, which works by having the client prepend a given string to each key in a command. It works in the same way that Ruby's redis-namespace does. This client-side approach still puts all your keys into the same database, but at least you add some structure, and you don't have to use multiple databases or servers.

var fooRedis = new Redis({ keyPrefix: 'foo:' });
fooRedis.set('bar', 'baz');  // Actually sends SET foo:bar baz
