Webinar: Secrets of ClickHouse Query Performance

Webinar: Secrets of ClickHouse Query Performance

ClickHouse is famous for speed. That said, you can almost always make it faster! This webinar uses examples to teach you how to deduce what queries are actually doing by reading the system log and system tables. We’ll then explore standard ways to increase query speed: data types and encodings, filtering, join reordering, skip indexes, materialized views, session parameters, to name just a few. We hope you’ll enjoy the first step to becoming a ClickHouse performance guru!

Webinar: Introduction to the Mysteries of ClickHouse Replication

Built-in replication is a powerful ClickHouse feature that helps scale data warehouse performance as well as ensure high availability. This webinar will introduce how replication works internally, explain configuration of clusters with replicas, and show you how to set up and manage ZooKeeper, which is necessary for replication to function. We’ll finish off by showing useful replication tricks, such as utilizing replication to migrate data between hosts.

Webinar: ClickHouse and the Magic of Materialized Views

Webinar: ClickHouse and the Magic of Materialized Views

Materialized views are a killer feature of ClickHouse that can speed up queries 200X or more. Our webinar will teach you how to use this potent tool starting with how to create materialized views and load data. We’ll then walk through cookbook examples to solve practical problems like deriving aggregates that outlive base data, answering last point queries, and using AggregateFunctions to handle problems like counting unique values, which is a special ClickHouse feature.

Webinar: Analyzing Billion Row Datasets with ClickHouse

Webinar: Analyzing Billion Row Datasets with ClickHouse

This talk shows how to get a sub-second response from datasets containing a billion rows or more. We’ll start with defining schema and loading quickly data in parallel. We will then introduce tricks like LowCardinality datatype, ASOF joins, and materialized views that can reduce query response to thousandths of seconds. Finally, we’ll show you metrics and logging to analyze query performance. After this talk you’ll be ready for your first billion rows and many more afterwards

Webinar: A Fast Intro to Fast Query with ClickHouse

Webinar: A Fast Intro to Fast Query with ClickHouse

Extracting business insight from massive pools of machine-generated data is the central analytic problem of the digital era. ClickHouse data warehouse addresses it with sub-second SQL query response on petabyte-scale data sets. In this talk we’ll discuss the features that make ClickHouse increasingly popular, show you how to install it, and teach you enough about how ClickHouse works so you can try it out on real problems of your own. Cool demos (of course) and Q&A at the end.
