The plan is to 10x that volume in the not too distant future but given what you've said I can believe we are horribly over-provisioned/over-scaled. Thank you!
It sounds like you’re probably using Clickhouse Cloud? If so, I was not impressed. Overly pushy sales people, pricing isn’t competitive, and they’re trying to cater to the snowflake/databricks crowd without smoothing any rough edges (like the default timeout being enabled on a GUI).
Overall I’d say CH isn’t as tolerant or forgiving as BigQuery, Snowflake, or Databricks. You can write the worst SQL possible and BQ will happily charge you $5/TB for that cartesian self-join. CH meanwhile will error with memory limit or even crash.
We are using Altinity. I believe it's a 3-server cluster and we have 2 clusters (our prod one and another one we are trying to promote to production once our data integrity checks pass, at which point we will spin the other down).
Robert Hodges of Altinity will likely be here shortly, they monitor HN for any mention of clickhouse, maybe they can get you fixed up without their standard $10k/mo support contract.
Hi Josh, sorry to hear about the issues. Sounds like things that should be solvable. ClickHouse does require thinking a bit differently from other stores like BigQuery. I sent you an email. Feel free to contact me at the email posted on my HN account. Looking forward to helping you bend ClickHouse to your will.
