We've been using ClickHouse ReplacingMergeTree tables for updates without any issues...in fact, they've been more than reliable for our use case. For us, as long as updated data is visible within 15–30 minutes, that's acceptable. What's your ingest vs. update volume per hour and per minute?
I agree, I’ve been on CH since v20 and I thought I was the only one who noticed that they’ve been working very hard to bridge the gap between OLAP and OLTP. Sure, they’ll always be first class OLAP DB…but if you know how to get dangerous with its strengths, making it the goto datalake for your existing OLTP is pretty freaking awesome. Thanks for those shares
