I had also assumed that SAL drives replication to page servers so that the compute knows exactly which version a page server is caught up to so that it can avoid sending reads to servers which don’t have the data yet. They wanted to batch updates to page servers, which adds replication delay, so…

I’m surprised you especially weren’t offended by their “our reconfiguration-based replication protocol has 100% availability” argument :p

I'd even settle for someone just updating the number on Rusty's nearing 20 year old "To BLOB or Not To BLOB"

Kuzu just folded/pivoted.

Me thinking a startup has promising tech has so far been a kiss of death to the company. An "Inverse Alex's Tech Opinions" fund might be very profitable. 🤔

Cool!!! I'll give it a try sometime over the next few days when I have a good chunk of time and let you know how it goes!

swiftwave.org looked interesting for small and simple self hosting

I will note that “scan sharing” seems specifically inter-query. If you have a single query that scans the same table multiple times and you want to coalesce that to scanning only once, that seems to be classified under subplan reuse instead?
E.g. link.springer.com/content/pdf/...

I think you’re talking about scan sharing? 15721.courses.cs.cmu.edu/spring2016/s...

I don’t know the OG citation for this. Andy cites graphs from 15721.courses.cs.cmu.edu/spring2016/p... and ir.cwi.nl/pub/12225/12... also looks pretty reasonable.

Err, I mean, I guess Yugabyte is also not linearizable and snapshot isolation, but just because of HLCs being inaccurate. LeanXcale is very intentionally not linearizable, and they mention that you have to do some extra work to even get session consistency out of it.

There’s a database startup called leanXcale which is the only non-linearizable snapshot isolation system that I know of. www.sciencedirect.com/science/arti... is a pretty decent overview, but there’s a YouTube talk somewhere too.

Do you think he’s just been “I told you so”-ing people since 1964? 😂

If you’re not ramped up on WCOJ algorithms, a lot of the papers are complicated to get through, but I thought TreeTracker Join arxiv.org/pdf/2403.01631 was pretty comprehensible and shows the minimal difference for NLJ. Or see justinjaffray.com/a-gentle-ish...

Even as a disliker of YouTube videos as a way to learn things, I found www.youtube.com/watch?v=-XmJ... easier to understand than the paper www.cs.ox.ac.uk/dan.olteanu/... for factorized database work

Extending SQL to Return a Subdatabase dl.acm.org/doi/pdf/10.1... also seems related?
