This is a free cache for Socrata open data portals.
All tabular (CSV, TSV, etc.) datasets available on every Socrata
open data portal are available here, with several improvements:
Gzip compression. This can reduce the amount of data
transferred from several gigabytes to just a few hundred
Pre-caching, when possible. This can seriously reduce
the time between request and response, which can be up to several
minutes for multi-GB datasets on a Socrata portal.
The cache is constantly updating. It should never serve out
outdated data. If data on the source portal has been updated since
the last time the cache grabbed it, the response won't be
pre-cached but it will still be gzip compressed.
All code is free and
on GitHub. You are welcome to run your own. The cache is
nothing more than nginx for gzipping and serving the frontend,
AWS S3 for caching, and some shell scripts for warming up.
