eBay depends on Kafka to solve the impedance mismatch between rapidly arriving messages in event streams and efficient block insert into ClickHouse clusters. Naïve loading procedures from Kafka to ClickHouse generate non-deterministic blocks, leading to data loss and incorrect results in applications. Learn how the eBay team solved this problem.
ClickHouse is open source. You can build it yourself. What’s more, you can make it better! In this webinar, we’ll demonstrate how to pull the ClickHouse code from Github and build it. We’ll then walk through how to contribute and more!
Window functions have arrived in ClickHouse! Our webinar will start with an introduction to standard window function syntax and show how it is implemented in ClickHouse. We’ll next show you problems that you can now solve easily using window functions. Finally, we’ll compare window functions to arrays, another powerful ClickHouse feature.
Kubernetes is a powerful platform for big data and is particularly well-suited for ClickHouse. If you have been wondering about trying Kubernetes, this webinar is for you. The first half introduces Kubernetes basics while the second half focuses on ClickHouse. You’ll learn everything you need to start grappling with big data on Kubernetes. Please join us!
Predictive analytics are popular in applications ranging from real-time marketing to factory maintenance. The key challenge is to integrate machine learning with the pools of data required to train models. In this webinar, we will show how to operate machine learning models from within ClickHouse using MindsDB.

Security and privacy are critical considerations in modern data warehouses. Join us to learn about ClickHouse security best practices including locking down servers, at-rest and in-flight encryption, and preventing information leaks through logs and system tables.
Data loading is a critical topic when building real-time data warehouses on ClickHouse. This webinar covers three ClickHouse topics every app designer should understand: insert performance, transaction reliability, and data deduplication.
Arrays are a prominent ClickHouse SQL extension that can accelerate query speed up to 100x in well-chosen use cases. This webinar introduces ClickHouse arrays and shows how to use them effectively. We provide examples of idiomatic usage and guides you on use cases where you should immediately reach for arrays. Watch the replay to become a power user of this popular ClickHouse feature.
We’ll talk about our experience building a next-generation OLAP capability for eBay event data using ClickHouse and realizing large infrastructure savings compared to the previous-generation solution built on Druid. Given the scale of eBay, this requires a highly scalable, performant and reliable Online Analytical Processing (OLAP) engine. Watch the replay to hear the whole story!
