ClickHouse clusters apply the power of dozens or even hundreds of nodes to vast datasets. In this webinar we’ll show you how to use the basic tools of replication and sharding to create high performance ClickHouse clusters. We’ll study the plumbing of inserts into sharded datasets and how to determine the correct number of shards for your desired writes. We’ll similarly look at distributed queries and show how to scale read capacity to desired levels using replicas. Finally, we’ll look at techniques for scaling up both shards and replicas to accommodate growth in your dataset.
