It sounds like you're doing something similar to how Databricks works now that they've acquired neon, or Snowflake now that they got Crunchy. I'm guessing the local SSD is a big advantage, but what else is different with your approach?
Thanks for posting this question! Compared to Snowflake and Databricks, a few key differences in our approach are:
(a) An initial focus on real-time, customer-facing applications rather than trying to boil the ocean. This also aligns with where the Postgres + ClickHouse combination has really shined for our users. Both Postgres and ClickHouse are designed primarily with developers building their system of record applications.
(b) Every component in the stack is open source—Postgres, ClickHouse, PeerDB for native CDC, pg_clickhouse, and Ubicloud Postgres (our data plane component). We plan to keep it that way as much as possible, as this strongly aligns with our ethos.
(c)Third, as you noted, Postgres is NVMe-backed and the focus is on performance and scalability, while maintaining top-notch reliability. We think that this more meaningful to fast-growing (AI-driven) workloads than instant provisioning and forking. I talk about this a bit more here - https://clickhouse.com/blog/postgres-managed-by-clickhouse#p...
Thanks! Out of curiosity, does the NVME have a big effect on replication throughput? I've been wondering how much trouble I've had with other solutions is due to parsing WAL and how much is just slow cloud disk
Very interesting question. Depends on the use-case, have seen quite a few workloads where logical replication gets throttled on I/O (reorder buffer) where NVMe based disk access should help a lot. This happens specifically when there are larger or interleaved transactions. We plan to test this at production scale soon. Stay tuned for more learnings!
Looks pretty awesome! Especially the native joins between warehouse tables and the OLTP db.
Will pricing likely just be a percent markup over the (excellent) Ubicloud prices they have listed? (https://www.ubicloud.com/docs/about/pricing)
Thank you for chiming in. Pricing is still TBD and will be finalized in the coming months before the service goes to GA. At a high level we plan to keep competitive also try to make it inclusive of the integration features too (native CDC + pg_clickhouse). Stay tuned!
congrats! the more postgres everywhere, the better
