Setting up a Collector
HOME > [SNOWPLOW SETUP GUIDE](SnowPlow setup guide) >> **Step 1: setup a Collector
The SnowPlow collector receives data from SnowPlow trackers and logs that data to S3 for storage and further processing. Setting up a collector is the first step in the SnowPlow setup process.
## 1. Choose a connectorThere are currently three collectors available:
| Tracker | Description | Status |
|---|---|---|
| [Cloudfront Collector] cloudfront-collector | A simple, robust and scalable collector powered by AWS Cloudfront | Production-ready |
| [Clojure Collector] clojure-collector | A Clojure-based collector that enables user tracking across domains. Powered by Amazon Elastic Beanstalk | Beta |
| [SnowCannon (node.js)] snowcannon | A real-time, node.js based collector that enables user tracking across domains | Beta |
If you are tracking users across a single domain, we recommend setting up the [Cloudfront collector] cloudfront-collector.
If you are tracking users across multiple domains, we recommending setting up the [Clojure collector] clojure-collector. This sets user_ids server side, so you can reliably track user journeys across multiple domains. (In contrast, the [Cloudfront collector] cloudfront-collector) sets them client side, so users get assigned different user_ids on different domains.)
Like the [Clojure Collector] clojure-collector, SnowCannon snowcannon supports user tracking across multiple domains. It also generates logs in real-time. Currently, however, the log file format is not supported by the [EmrEtlRunner] [emretlrunner], making integrating SnowCannon with downstream data processing modules tricky. We will be addressing this in the next few months.
## 2. Setup your connector- [Setup the Cloudfront collector now!] cloudfront-collector
- [Setup the Clojure Collector now!] clojure-collector
- [Setup SnowCannon now!] snowcannon
Setup your collector? Then proceed to [step 2: setup a tracker] tracker-setup.
