Successful MySQL applications have a very common scale problem: how to provide analytics when data grows too large for MySQL to handle. Fortunately, there is a good answer. ClickHouse is a popular, open source column store you can use to add fast analytics to MySQL applications. We'll start with an introduction to ClickHouse for MySQL users showing familiar SQL syntax and table engine design. We'll then walk through important features like support for MySQL wire protocol, ability to read data directly from MySQL tables, and different ways to move data from MySQL into ClickHouse. Finally, we'll touch on design approaches that allow you to extend MySQL applications with analytics that can handle billions of rows.
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. In each case we'll circle back to query plans and system metrics to demonstrate changes in ClickHouse behavior that explain the boost in performance. We hope you'll enjoy the first step to becoming a ClickHouse performance guru!
This topic is so important, that we decided to do this webinar twice! Read more to pick your time.
Simplified management is a prerequisite for running any data warehouse at scale. Altinity is developing a new web-based console for ClickHouse called the Altinity Cluster Manager. It's now in beta and offers simplified operation of ClickHouse installations for users. In this webinar we introduce the ACM and demonstrate use on Kubernetes as well as Amazon Web Services. Attendees are welcome to sign up as beta testers and provide feedback. Please join us to see the future of Clickhouse management!
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. Join us to become an expert in this important subject!
June 26, 2019 By Robert Hodges and Altinity Engineering Team Speaker: Robert Hodger, Altinity CEO 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. There will be time for Q&A at the end. At that point you'll be a wizard of ClickHouse materialized views and able to cast spells of your own.
June 5, 2019 Speaker: Robert Hodges, Altinity CEO 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.
April 16, 2019 Speaker: Robert Hodges, Altinity CEO Data services are the latest wave of applications to catch the Kubernetes bug. Altinity is pleased to introduce the ClickHouse operator, which makes it easy to run scalable data warehouses on your favorite Kubernetes distro. This webinar shows how to install the operator and bring up a new data warehouse in three simple steps. We also cover storage management, monitoring, making config changes, and other topics that will help you operate your data warehouse successfully on Kubernetes. There is time for demos and Q&A, so bring your questions. See you online!
March 6, 2019 Speaker: Robert Hodges, Altinity CEO 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. We'll have cool demos (of course) and gladly answer your questions at the end.
