The transaction must enter the system somewhere. The 'coordinator' is that entry point, with a durable log so we don't inadvertently lose the transaction. It's only job is to push the transaction to all the workers invol

Interesting. This assumes there is a way to do consistent remote reads, that is some way to implement B.read(value=y, tx=T). Additionally, this works without using a global sync point, as per your other message. Naive implementation: * B ju

Perhaps I'm not getting the setup right. Assuming that data is partitioned between worker A and worker B, I see no way to rewrite a distributed transaction to proceed based strictly on information available to A or to B. T(

Perhaps I'm not getting the main point right. Looks like the proposal is a minor optimization of the 2PC protocol, where a worker ACKs the transaction as soon as possible, presumably somewhere between updating the durable log and updat

Surely somebody in the '90s said something similar with regard to location data, and yet your location is tracked 24/7 by adtech megacorps, and the thousands of tech/adops employees don't say a peep. The playbook has 3 e

FWIW, there is [used to be?] a git interface for the centralized monorepo. Really handy for managing multiple dev braches at the same time.

Pinning dependencies is easy, and gets one stuck on Java 1.3 and IE 6. Since the library maintainer doesn't know it broke dependent code, the dependent code will be unlikely to have a smooth upgrade path. It's just a matter of hav

Thanks for providing a great example of useful getters. If you're computing a derived property that depends strictly on the data at hand and its attributes, getters are useful. When designing code, follow the Getter Idempotency Princip

Technically speaking, what's a good way to connect to data sources for cloud apps? I'd be nervous to let cloud apps [or hackers thereof] to slurp arbitrary bits of data through JDBC. Quite a bit more comfortable having the connect

It's a lot of fun to be in your '50s, have your body start to fall apart and be a few paychecks away from being thrown into the streets. But hey, you could afford having a few beers with your friends in your '20s. Or even tak
