Today I am going to show how to get AVRO data from a schema aware Confluent Cloud cluster into Apache Druid. Use the Druid 0.22 micro-quickstart setup for this exercise.

The other day, Peter Marshall brought up a question: Do lookups work with multi-value dimensions in Druid? Spoiler alert: They do, in fact! But let’s first take a quick look at what lookups are.

In this short post I want to take a closer look at Imply Pivot and how to address a common scenario for analytics: Let’s assume we want to filter on a dimension value, but we want to exclude rather than include a set of dimension values.

Let’s do some customer segmentation in our little restaurant!

In which we continue the quest about multi-value handling and try to answer the question: Why are we even doing this?
