I don't know about ClickHouse specifically but these days it isn't that hard to ingest >10M rows/sec per server, including parsing, processing, indexing, and storage. You can just throw hardware at it.

yeah I mean that's basically what Javi talks about in the post... if you can throw hardware at it you can scale it (ingestion scales linearly with shards)
but the post has some interesting thoughts on how you do the high-scale ingestion while also handling background merge processes, reads, etc.
