Hi

I'm of the guy who did the 2 presentations of Clickhouse at ContentSquare. There are no blog posts on the migration from ES to CH. But you can find the slides of the 2018 presentation here https://www.slideshare.net/VianneyFOUCAULT/clickhouse-meetup... And the slides of the 2019 presentation here https://www.slideshare.net/VianneyFOUCAULT/meetup-a-successf...

There is also a video recording of the 2019 presentation available here. https://www.youtube.com/watch?v=lwYSYMwpJOU nb: The video is not great because the camera is often losing focus but it's still understandable.

I'm not sure there is a public writeup. I know that the incredibly talented guy who created the first CH setup at CS planned to write a more global post about data analytics at scale, but after 2 years I still wait for it

I stopped answering to people about the release date of my next blog post because I'm always postponing it ;-).

But don't worry Paul, the day I'll release it you'll be one of the first to be informed.

I'll remind him about the post ;)
