Learn how the Data Infrastructure team at Brandwatch rearchitected a group of their current Solr clusters and took a new approach in an unconventional manner. By splitting up the reads and writes, experimenting with Solr plugins, using S3, an application written in Rust and adopting the Solr Operator to spin up a cluster on Kubernetes, we were able to achieve our goal of having a cloud-based cluster which comfortably serves 26bn+ documents. You'll understand the whys of our approach, things we discovered, what we have planned, and why rearchitecting things can be a difficult and strenuous task.
