One more follow-up on the scale side (which I mentioned with sibling comment), it isn't so much about clickhouse itself, but about scaling up ingest. From my own experience and from talking with quite a few APM players (I previously worked in streaming space), a Kafka / durable log storage kind of becomes a requirement, so I was curious if you think at some point you need a log to further scale ingest.
For enterprise side, I was previously in data streaming space and had quite a few conversations with APM players and companies building their own observability platforms, happy to chat and share more if that would be useful!
