# Deep Dive on ClickHouse®: Sharding and Replication Webinar

**Recorded:** Thursday, September 22, 2022  
**Presenters:** Robert Hodges & Altinity Support Engineering

Join the Altinity experts as we dig into ClickHouse sharding and replication, showing how they enable clusters that deliver fast queries over petabytes of data. We’ll start with basic definitions of each, then move to practical issues. This includes the setup of shards and replicas, defining schema, choosing sharding keys, loading data, and writing distributed queries. We’ll finish up with tips on performance optimization.

**Here are the slides:**
