Creating an entity-centric index that contains only the latest document for each entity can be useful in a number of situations. For example, maybe you're managing an ecommerce site and you want to track the latest order placed by each of your customers. Or maybe you want to run a campaign targeting customers who haven't been active over a certain period. What's the fastest and most efficient way to compile and organize such data? Transforms in Elasticsearch enable you to create and maintain an
In January 2021, we announced that starting with version 7.11, we would be changing the Apache 2.0 portions of Elasticsearch and Kibana source code to be dual licensed under Elastic License and SSPL, at the users’ discretion.

In our last episode, I wrote about some speed improvements to date_histogram and I was beside myself with excitement to see if I could apply the same principles to other aggregations. I've spent most of the past few months playing a small part developing runtime fields but eventually I found time to take a look at the terms aggregation. It's time for terms!With the date_histogram aggregation we got a huge performance boost by rewriting it as a filters aggregation internally. Rewriting terms as
As a quality assurance engineer on the Kibana team at Elastic, Bhavya Raju Mandya makes an effort to see things from a different perspective. “My job is to break things,” says Bhavya. “I like impersonating a cat, being curious, seeing what happens if I knock something off, or moving something or changing the order to figure out what gives. The end goal is to protect and defend the quality of Kibana and that makes me happy.” The value Bhavya places on curiosity and diverse perspectives is a
