HN discussionCraig here from Crunchy. Pretty excited to ship this. It started with one of our engineers showing up in slack 6 weeks ago "So I did something crazy over the weekend..." from there it evolved into much more. The post explains a lot of the high level, but we're going to being doing some deeper dives as well including the build process, but also some of how the tutorials are powered by an internal notion doc which all…

HN discussionOur Postgres is pretty great up to about 500GB. We'll be pushing that higher over the next year, but we have several customers using Crunchy Data ( https://www.crunchydata.com/products/crunchy-bridge/ ) in conjunction with their Fly.io apps. We intentionally give you super user access to your DBs so it's easy to migrate or spin up your own replicas. Our bet is that _most_ people won't outgrow our Postgres but having…

HN discussionThat requires data to already be in Postgres, otherwise you have to ETL data into it first. DuckDB on the other hand works with data as-is (Parquet, TSV, sqlite, postgres... whether on disk, S3, etc.) with requiring an ETL step (though if the data isn't already in a columnar format, things are gonna be slow... but it will still work). I work with Parquet data directly with no ETL step. I can literally drop into Jupy…

HN discussionI just gave it a try to install on Crunchy Bridge [1], disclaimer I work at Crunchy Data. I did this as a standard user vs. anything special about access. I got quite close, but looks like I'm limited by Python version, we give you plpython3u with Python 3.6. Is there any chance of supporting an earlier 3.x version? If so I'm pretty sure could give a guide on how to self-install on top of us. [1] https://www.crunchy…
