Elasticsearch's date_histogram aggregation is the cornerstone of Kibana's Discover. And the Logs Monitoring UI. I use it all the time to investigate trends in build failures, but when it is slow I get cranky. Four seconds to graph all of the failures of some test over the past six months!

Let’s say you get an alert that one or more queries is slow. Or that your users complain, whichever comes first 🙂 We’ve all been there… How do you find the root cause for this slowness and then fix it? In this article, I’ll go through my usual thought process: first, I’d try to find which queries are slow. Then, I’d dig deeper: Let’s take a specific example and run through each step.

We are moving our Apache 2.0-licensed source code in Elasticsearch and Kibana to be dual licensed under Server Side Public License (SSPL) and the Elastic License, giving users the choice of which license to apply. This license change ensures our community and customers have free and open access to use, modify, redistribute, and collaborate on the code.

Indexing the web is hard. There’s a nearly infinite supply of misbehaving sites, misapplied (or ignored) standards, duplicate content, and corner cases to contend with. It’s a big task to create an easy-to-use web crawler that’s thorough and flexible enough to account for all the different content it encounters.

Today’s cars are computers on wheels, and they’re powered by software as much as they are by batteries or gasoline. When it comes to building software for Audi, Volskwagen, Porsche, Traton, and other brands, that’s a task assigned to Audi Business Innovation (ABI). “Developers need the right tools in their hands that are easy to use,” says Stefan Teubner, an ABI team leader and DevOps engineer.
