Elasticsearch is a fantastic tool but it's easy to muddle through without knowing the fundamentals. It's only a matter of time before your cluster performance drops, errors start happening, and you wonder just what a shard actually is.

I talk and wave my hands about, explaining how we could have - maybe - built - some of - Elasticsearch ourselves. At the end of the video you'll know what a shard is, why they're so important, and want to learn more to really improve the performance of your cluster.

Watch on (and watch the rest of the free course linked below) to figure out how to answer that mysterious question: How many primary shards do I need for my index?
