Nested Data Structures in ClickHouse

In this blog post, we’ll look at nested data structures in ClickHouse and how this can be used with PMM to look at queries.

You might have heard about Brendan Gregg’s USE Method  (Utilization-Saturation-Errors) as a way to analyze the performance of any system. Our goal in PMM is to support this method fully over time, and these graphs take us one step forward.
