Advertising is dying in the wake of privacy and adblockers. Join us for a conversation with James Hartig, a Co-Founder at Admiral, who helps publishers diversify their revenue and build more meaningful relationships with users. We'll start with an overview of Admiral's platform and how they use large scale session data to power their engagement engine. We'll then discuss the ClickHouse features that Admiral uses to power these real-time decisions. Finally, we'll walk through how Admiral migrated from MongoDB to ClickHouse and some of their plans for future projects. Join us to learn how ClickHouse drives cutting edge real-time applications today!
The market for scalable SQL data warehouses is dominated by proprietary products. ClickHouse is one of the first open source projects to give those products a run for their money. ClickHouse scales to hundreds of nodes with ingest measured in millions of events per second. The user community includes CloudFlare, Cisco, and numerous financial services companies. This talk briefly recounts the history of ClickHouse, starting with its origins at Yandex, then dives into popular features. These include column storage with efficient data encoding and compression, vectorized query execution, sharding and replication, and materialized views. We will end with a short survey of popular use cases and questions.
Robert Hodges is the CEO of Altinity, a venture-backed start-up that markets ClickHouse to enterprises. He is also a database geek who has used or worked on over 20 different database systems. Other interests include distributed systems, Kubernetes, and open source. He is an organizer of the San Francisco ClickHouse meetup.

ClickHouse is famously fast, but a small amount of extra work makes it much faster. Join us for the latest version of our popular talk on single-node ClickHouse performance. We start by examining the system log to see what ClickHouse queries are doing. Then we introduce standard tricks to increase speed: adding CPUs, reducing I/O with filters, restructuring joins, adding indexes, and using materialized views, plus many more. In each case we show how to measure the results of your work. There will as usual be time for questions as well at the end. Sign up now to polish your ClickHouse performance skills!

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.

You are about to deploy ClickHouse into production. Congratulations! But what about monitoring? In this webinar we will introduce how to track the health of individual ClickHouse nodes as well as clusters. We'll describe available monitoring data, how to collect and store measurements, and graphical display using Grafana. We'll demo techniques and share sample Grafana dashboards that you can use for your own clusters.

Materialized views are the killer feature of ClickHouse, and the Altinity 2019 webinar on how they work was very popular. Join this updated webinar to learn how to use materialized views to speed up queries hundreds of times. We'll cover basic design, last point queries, using TTLs to drop source data, counting unique values, and other useful tricks. Finally, we'll cover recent improvements that make materialized views more useful than ever. See you there!
