Google's Matt Cutts On Percolator, Dremel & Pregel

I doubt this will help you with your SEO and rankings but hey it is always fun hearing an engineer talk about some really technical details about how certain things are used at Google.

In his latest video, Matt answers how Google uses Percolator, Dremel and Pregel?

Here are the technical documents on each:

• Percolator: Large-scale Incremental Processing Using Distributed Transactions and Notifications
• Dremel: Interactive Analysis of Web-Scale Datasets
• Pregel: a system for large-scale graph processing

Here is how Matt sums it up in four minutes:

Google: Keep URL Length Shorter Than 2,000 Characters

SEOs obsess about the smallest things, even how long is too long for a URL.

A Google Webmaster Help thread has SEOs and webmasters asking how long can they go for a URL. Google actually answered the question.

John Mueller of Google said, while there is "no theoretical length limit" and they can go forever, Google does recommend you keep it under 2,000 characters. Google's John Mueller wrote:

As far as I know, there's no theoretical length limit, but we recommend keeping URLs shorter than 2000 characters to keep things manageable.

It is interesting cause DoubleClick, a Google company, maxes out on 2,000 characters in a URL. It seems the GET method maxes out on 2,000 characters for a URL and that Internet Explorer can't go beyond 2,000.
