In this video, we'll learn all about working with arrays in ClickHouse. Starting with an overview of the array functions documentation, we dive into practical examples using a weather measurements dataset. Key topics include querying, grouping, and manipulating arrays to extract valuable insights like maximum and minimum temperatures, weather conditions, and more. The functions covered in this video include array_slice, array_max, array_min, array_filter, array_join, array_flatten, array_compact, and array_distinct.

I'm currently storing 4 columns with the same data, in raw, flattened, compacted and distinct, with this knowledge I can reduce my storage by over 60% - nice one!!
