> We built chproxy specifically because ClickHouse doesn't like thousands of tiny inserts. It's a Go service that buffers events and sends them in large batches. Each Cloudflare Worker would send individual analytics events to chproxy, which would then aggregate and send them to ClickHouse.

While I understand how this isn't the only thing that needed to be buffered, for Clickhouse data specifically I'd be curious why they built a separate service rather than use asynchronous inserts:
