dynalite

dynalite

A mock implementation of Amazon's DynamoDB, focussed on correctness and performance, and built on LevelDB (well, @rvagg's awesome LevelUP to be precise).

All basic actions and validations have now been implemented, but there are still a number of issues (see below) before this module should be considered for general use.

Example

$ PORT=8000 dynalite  # defaults to port 4567

Or programmatically:

// Returns a standard Node.js HTTP server
var dynalite = require('dynalite'),
    dynaliteServer = dynalite({createTableMs: 50})

// Listen on port 4567
dynaliteServer.listen(4567, function(err) {
  if (err) throw err
  console.log('Dynalite started on port 4567')
})

Installation

With npm do:

$ npm install dynalite

TODO

• Add config settings, especially for the table delays and strict checking
• Allow for different persistence types (LevelDOWN-Hyper, etc)
• Use efficient range scans for Query calls
• Implement ReturnItemCollectionMetrics on all remaining endpoints
• At what point does BatchGetItem#UnprocessedKeys get triggered?
• Is the ListTables limit of names returned 100 if no Limit supplied?
