CurryProxy

A fast and performant proxy and aggregator for querying multiple instances of an API spread across globally distributed data centers.

Capabilities

• CurryProxy can handle multiple routes for use against different revisions of an API or for use against completely unrelated APIs. See etc/routes.sample.json for an example configuration.
• Simple request forwarding (useful for preserving backwards compatability with pre-CurryProxy versions of an API hosted in a single datacenter)
  • Example: GET https://api.example.com/v1.0/foo/bar forwarded to GET https://1.api.example.com/v1.0/foo/bar
• Advanced request forwarding to multiple endpoints
  • Example: GET https://api.example.com/1,2/v1.0/foo/bar forwarded to the following:
    • GET https://1.api.example.com/v1.0/foo/bar
    • GET https://2.api.example.com/v1.0/foo/bar
  • Requests are made in parallel
  • JSON responses received from multiple endpoints are aggregated and returned to the client
    • Example: {"foo": 1} received from 1 and {"bar": 2} received from 2 are aggregated to [{"foo": 1}, {"bar": 2}] and returned to the client
  • Rich, meaningful errors logged and returned to the client when a proxied request fails

Installation

• pip install curryproxy
• Setup the configuration files and start it up!

Limitations

• Merging responses from multiple endpoints together occurs only under certain conditions outlined on the Multiple Endpoints Aggregation wiki page.

Roadmap

• OData support for server-side ordering and paging
• Response caching for a specified time
