To create a Redis databank, use the Databank.get() method:

var Databank = require('databank').Databank;

var db = Databank.get('redis', {});

The driver takes the following parameters:

  • host: the host to connect to; default is
  • port: the port to connect to; default is 6379.
  • schema: the database schema, as described in the Databank README.
  • database: integer representing the Redis database to use; default is 0.

See the main databank package for info on its interface.

Under the covers

Keys in the database have the form "type:id". So a "person" with id "evanp" is at "person:evanp".

Objects and arrays are stored as JSON-encoded strings in the Redis database. Numbers are stored as numbers.

Indices are implemented as sets. Search uses set intersection to quickly find keys to matching objects.

Something went wrong with that request. Please try again.
