Before I started working full time as a Developer Advocate, I had never come across the term BBL. Just reading the title of this post should already disprove the theory that it belongs exclusively to the medical world. It turns out that it does not.
So what exactly is a BBL and what is it not?
NoSQL for years was associated with JSON. The thing is: if you’re a hardcore backend Java developer, JSON, YAML, and other data formats might not feel native to you. Also, if you were ears-deep into debugging a query from Java code, sending the same request for visualization in Kibana using KQL wasn’t trivial. Meet ES|QL: Elasticsearch’s new query language, being at first glance a mixture of SQL and… Bash ;-) Works the same in Java and Kibana (and other programming languages too!) Additionally, by leveraging Project Valhalla and vector operations, ES|QL can achieve performance improvements over previous solutions. If you’re eager to investigate the options of the ES|QL and how it makes your life easier (while also giving a feel of being a SQL DB), this talk is for you.
If I got a dollar every time I hear “we had to disable security and authentication in Elasticsearch because otherwise it was unusable”, I’d be a bit richer by now ;-)
Honestly, I don’t quite get where the confusion comes from. It’s 2024, yet some of us are still surprised by “what do you mean: certificate and password???”
Let me explain security in Elasticsearch in a few simple paragraphs.
