We’re rolling out a series of performance improvements to ScraperWiki.

Yesterday, we sped up the Tableau/OData connector.

Today, it’s the turn of the humble CSV.

When you go to “Download a spreadsheet” you’ll notice the CSV file is now always described as “live”.

This means it is always up to date, and streams at full speed to your browser. Even free account users don’t need to press the refresh button any more.

If you’ve any external software that automatically downloads the CSV file, you’ll want to update the URL it reads from.

(Developers note: It even sets the little known ‘header’ parameter of RFC4180! And our code is a extreme short call out to the SQLite binary.)
