When we announced our license change for Elasticsearch and Kibana, moving the Apache 2.0-licensed source code to be dual licensed under both the Elastic License and SSPL, we also mentioned we would work closely with the community on a simplified and more permissive version of the Elastic License. I am happy to share the results with you. The Elastic License is already widely used.

Elastic is “an index”, “a search engine”, “a big data solution”, an analytics platform with advanced data visualizations and incredibly fast search capabilities. In short, it’s a solution for many problems. The Elasticsearch platform provides a distributed search cluster that enables large amounts of data to be indexed and searched at scale.

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! I don't have time for that! Who is going to give me my four seconds back?! So I spent the past six months speeding it up. On and off.

Shell International knows that it takes cutting-edge technology to thrive in the competitive, global energy industry. With projects around the world, in both renewable and non-renewable energy, Shell must always have insights into the future. From determining expected output to predicting equipment failures, there's no room for guessing in an industry where downtime is unacceptable.

The recent changes to the Elasticsearch license could have consequences on your intellectual property. On the 14th of January 2021, Elastic announced through their blog that Elasticsearch and Kibana will be moving over to a Server Side Public License (SSPL). This license change, effective from Elasticsearch version 7.11, has business owners that rely on the ELK stack rightly concerned.

With Elastic App Search, you can add scalable, relevant search experiences to all your apps and websites. It offers a host of search result personalization options out of the box, such as weights and boosts and curations. You could also add a these documents might interest you feature, which would surface additional content for users, similar to documents they’ve previously searched for. This post walks you through the process of creating this capability using the robust App Search APIs.

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.
