Exploding arrays in Kafka with lateral joins

In this article we are going to explore lateral joins. "What is a lateral join?" you may ask. It's a new kind of join that allows to extract and work with the single elements found inside an array, as if the array was a normal table. Lenses 4.1 comes with a lot of new features that make your life easier when working with arrays: we introduced 6 new functions to work with arrays, better support for array literals, and lateral joins.

How to add Bugfender to an Android Project

Adding Bugfender to an Android project is a two-minutes task that can save you hours of debugging in production. In this video we review the whole process from scratch. We start creating an Android app with Android Studio. Then we add Bugfender with Gradle and finally we configure a new App in the Bugfender's Dashboard. We use the last minutes to explain how the different logs work in Bugfender so you can get the most from the first minute.

How to configure clients to connect to Apache Kafka Clusters securely - Part 2: LDAP

In the previous post, we talked about Kerberos authentication and explained how to configure a Kafka client to authenticate using Kerberos credentials. In this post we will look into how to configure a Kafka client to authenticate using LDAP, instead of Kerberos. We will not cover the server-side configuration in this article but will add some references to it when required to make the examples clearer.
