Webinar. Strength in Numbers: Introduction to ClickHouse Cluster Performance
Webinar. Strength in Numbers: Introduction to ClickHouse Cluster Performance
April 29, 202
with Robert Hodges
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.

Webinar. MORE secrets of ClickHouse Query Performance
Webinar. MORE secrets of ClickHouse Query Performance
May 27, 2020
with Robert Hodges
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!

Time Series SF Meetup. Introducing ClickHouse–the fastest data warehouse you’ve never heard of
Time Series SF Meetup. Introducing ClickHouse–the fastest data warehouse you’ve never heard of
Abstract:
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.
Speaker Info:
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.
