> in addition to disaggregated storage s3 is authoritative storage for older data
But if you say "Disaggregated Storage on S3" then you have the flexibility to change that to "Disaggregated Storage on FOOBAR" to avoid confusion.
I've never seen "lake" or adjacent terminology refer to S3 specifically like that vs other object storage. A data lake on Ceph would still be a data lake.
(My quibble would be that "lake" often refers to inconsistent or unstructured, and itself has always been a bit handwavy compared to "warehouse," whereas this is very structured data on object storage.)
Maybe I’m wrong, but AFAICT this is block (page) storage backed by S3, tuned for Postgres with some paxos-linked storage/caching servers sitting in front? Sounds good, but I’m not sure “lake” or “warehouse” is a word I’d choose… much closer to Litestream-with-reads, or the somewhat-famous “I ran out of RAM so I downloaded some more” blog article.
