Webinar: A Practical Introduction to Handling Log Data in ClickHouse
December 17, 2019
with Robert Hodges
Log messages are one of the most important types of application data. ClickHouse is very good at storing log data; many SaaS applications use it under the covers. In this webinar we will show examples of different application logs and how to design tables to store them. Options include using typed columns, strings, JSON, or key-value pair arrays. We'll also discuss how materialized columns to improve filter speed, as well as techniques to tune index granularity for wide rows. This is the first in a series of webinars on log management. Future webinars will cover tools to load data as well as techniques to retrieve log information efficiently.

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.

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!
