Looks like this is slightly modified by the uploader: p94 says “Weaponize the cloud” with the Antimetal logo

Have you used osquery? Seems like a good chunk of what you’re looking for!

https://www.osquery.io/schema/4.7.0/

Immediately searched for “Nagle”, “TCP”, etc but was surprised to see this is something else! Not the typical TCP_NODELAY issue.

I don’t think this is a fair reason to write the tool off. They support Homebrew, and I’m sure will add other install methods in the future. Piping to bash is no worse than clicking “yes” on every step of an install wizard.

Using something like io-ts gives you the benefits of static types and runtime types. JSON Schema typically just provides runtime guarantees but doesn't come with the same development experience. I've been very happy with io-ts so far.

ML-assisted query optimization is super interesting to me (I've had to fight the uphill battle against anomalies in Postgres stats and estimations[1]), but I'd also love to see more optimization and auto-tuning across the "stack":

- Use column-oriented storage for columns that are frequently scanned in analytical queries

- Automated index management, based on user-provided boundaries for write throughput, disk footprint, query latency

- Calibrated optimism for heap updates. AFAIK, current DBs are either optimistic (assume transactions are more likely to commit than rollback) and update the heap in-place, and write the old value elsewhere in case of rollback, or pessimistically write all updates in new, versioned tuples and let MVCC (and garbage collection) handle the rest. Would be interesting to see the performance improvement that could come from modeling commit / rollback outcomes and optimizing accordingly.

- Using variable-sized pages to reduce overhead for older pages, as a sort of light cold storage

Anyone know of any DBs that automatically tune these aspects?

Terraform does let you destroy resources: https://www.terraform.io/docs/commands/destroy.html

I see some references to Presto, but does anyone know what this engine is based on? Seems vaguely similar to Druid but it's hard to tell.

Nope, they've been sharing their research more widely in the last few years. Here's an example from 2018, in a different area of research: https://www.vldb.org/pvldb/vol11/p540-shraer.pdf

Needs some sort of a demo or screenshot before I would consider signing up. Even better, let people lurk (read without creating an account) before joining.

What changes do you hope to see? When?

What does it mean for employees to "help implement the changes"?

What will you do if change does not happen?
