Yes, I think VCs have already switched to using other metrics that are less easy to fake, such as download per month or customer interviews (or more direct, ARR, even for really early stage startups). I just want to explain the background r

CGI/PHP treated database connections as something that's always available. That pushes a lot of hidden complexity onto the database platform: it has to be reachable from anywhere, handle massive fan-out, survive bursty short-lived

It's currently 3MB, and we've done almost nothing to reduce the file size, so we can expect it to get even smaller.

Owner of Tonbo here. This critique makes sense in a classic web-app model. What's shifting is workloads. More and more compute runs in short-lived sandboxes: WASM runtimes (browser, edge), Firecracker, etc. These are edge environments,

Sure I'd love to, could you share your practice or what you are doing on top of Parquet?

Thanks, easy-to-scale is the first thing we consider, also using S3 as a shared storage service makes architecture easy to achieve this.

We are building tonbo: https://github.com/tonbo-io/tonbo , An embedded KV database allows to use S3 as storage backend, and we are trying to implement SQLite virtual table on it: https://github.com/tonb

Random reads and sequential writes are enough to build a log-structured database, but S3 does not really support the latter.

the post only talks about "future state", maybe I'm not clearly to point out this. with epoll, accept syscall and future state changing is happened in the same polling, which io_uring is not. Once accept syscall is complete,
