Today, we have Philipp Krenn on the show. He's the head of DevRel for Elastic, and we took a deep dive on all the Elasticsearch stuff like Indexes, Mappings, Shards and Replicas and how to think about performance and all that stuff. We also discussed the Use Cases and applications where Elastic is not suitable to use. This episode is packed with fundamentals and we think you'd love it.
