Distributed transactions, that is, atomic commitment, look a lot like a distributed consensus problem:

All participants must either commit or abort a transaction 👤👤✔️❌

However, atomic commitment is quite different from consensus

Getting the nouns and verbs “just right” is crucial to a crisp, clear mental model for building (great!) distributed systems.

And this post by @DominikTornow is a sublime example:

“Concurrency is a statement about logical time, parallelism is a statement about physical time.”

[Dominik Tornow @DominikTornow]

Although the transaction is correct, it is *impossible for the caller to know if a transaction occurred* in the presence of a component or network failure 💀

We need to ensure end-to-end correctness ⛓️

Distributed systems are intrinsically different from non-distributed systems

🚧 Objects that interact in a dist sys need to be dealt with in ways that are intrinsically different from objects that interact in a non-dist sys 🚧

Are you a @MuhammadAli fan? If you are, here's a little-known story about the boxing legend and @NelsonMandela. It's from my book, The Plot To Save South Africa, which details a week in which South Africa came to the brink of civil war. And Muhammad Ali was there. 1/12

Check out my new blog post Handling Failures from First Principle.

The post presents a principled failure handling strategy that guarantees correctness & completeness while maximizing the chance of success in the presence of failure.

Some weekend fun 🤓

@DominikTornow Saw your excellent presentation from strange loop. IMO fault tolerance needs distribution and for fault tolerance it is essential break the algorithm in a series of steps which are check pointed. This automatically leads to workflows.

Another weekend, another weekend read, this time all about deleting 3 million lambda functions

When confronted with the problem of developing an url shortener, @kkuchta opted to use AWS lambda functions － now he is confronted with 3,351,105 problems 🤯

In the tug of war between Orchestration and Choreography, who wins? No contest: Orchestration. At least if you believe what @dominiktornow has to say in his #Replay2022 talk.

Another weekend, another weekend read, this time all about Hybrid Logical Clocks

@muratdemirbas et al introduce HLC: HLC captures the happened-before relation & maintains its logical clock to be always close to the physical clock.

@temporalio If you have your tickets already come join me for my talk on event driven application, orchestrations vs choreography, workflows vs sagas

The epic showdown 🔥

[Cory Doctorow NO LONGER ON TWIT TER @doctorow]

Uber just released its Q2-2022 numbers and trumpeted that it had finally achieved cash-flow positivity - and it only took 13 years and $32 billion in losses! So has Uber finally turned a corner? Will the company finally attain profitability and repay those billions?

Nope. 1/

[Adam Grant @AdamMGrant]

Falling short of a goal doesn't mean failure. Often it's progress.

14 experiments, 10k people: people counted results that didn't meet targets as losses—even if they were gains.

The key measure of success isn't reaching your destination. It's improving from your starting point.
