what is the storage model for prometheus

[andyxning]

I come into prometheus from a ppt about Golang.
After reading some introduction info about it, i am now wondering the storage model for prometheus.
I know that:

• Graphite uses whisper
• Cacti uses RRD
• OpenTSDB uses HBase
  How does the storage model for prometheus and any doc or code for it?

We are using our own storage layer, which has a very high throughput but is not intended for long-term storage.
Prometheus supports streaming metrics into InfluxDB or Graphite upon ingestion. This is just experimental though and without read-back support.

There's currently no white-paper documentation on our storage model.
Here are some slides that might help a bit but are lacking text for a good understanding without the surrounding talk: http://www.slideshare.net/FabianReinartz/prometheus-storage-57557499

I would be interested in that Go presentation that referenced Prometheus. Do you have a link?
