One of the goals of analytic applications is to get insight from newly arriving data as quickly as possible. In this talk we'll trace the path that data follows from ingest into ClickHouse to storage to returning back to users in query responses. We'll show how to make each step of the journey as quick and efficient as possible. You can expect to learn high impact tricks parallel data loading, async insert, fast compression, and query tuning. We'll also show you where to look if they aren't performing. Bring your questions!
