Your notes aren't very good. They're not a time series database company, they're a columnar database company. But yeah the LLM bit is weird, database companies _always_ feel like charlatans when it comes to LLMs.

ClickHouse effectively has a number of personas. Time series is one of them, and ClickHouse has steadily absorbed market share from pure play time series databases over the last few years. Other personas include real-time observability backend (the single biggest use case in my experience) as well as real-time data lake engine. Time series support, column storage, and real-time response are key underlying capabilities. It's quite versatile and fun to use.

Disclosure: I run Altinity, a vendor in this space.

(Update: Disclaimer -> Disclosure. Sigh.)

Altinity isn't just a vendor, it's THE ClickHouse vendor before ClickHouse became a company. https://altinity.com/blog/big-news-in-the-clickhouse-communi...

always nice to see a database ceo be "one of us" and/or "write like a real human being".

That's very kind of you. We love working on ClickHouse and real-time analytics.

Willing to bet most columnar stores are used for time series.

I suspect most use of columnar databases is OLAP, which is different from what people usually mean when they say time series data.

I’d take that bet
