dbStream.pipe(stdout()); // Just spit it to the console

dbStream.write({ a: 10 }); // Store a=10
dbStream.write({ a: null }); // Query for the value of a
dbStream.write({ a: "foo" }); // Store a="foo"
dbStream.write({ a: undefined }); // Delete a from store

API

var db = require('keev')({options});

options.store is a an object with the following methods. If a store it not given, it will assume a memory store.

A store must implement:

getAll(keys, cb)

where cb is a callback that with the signature (err, obj). For each key passed in the object will have a property, if a value is not found, it's value will be undefined.

putAll(obj, cb)

where cb is a callback that with the signature (err). For each key in the object, the store should delete the key if the value given is undefined, or set it otherwise.
