Think Distributed Systems - Review

I jumped straight to Chapter 11 on Durable Execution and hit a wall. Going back to Chapter 1 taught me why mental models matter more than memorizing patterns and frameworks. This review explains why y...

React vs. Backbone in 2025

the paradox with modern frameworks, trade transparency for abstraction, making it easy to start and hard to master. Abstraction helps beginners, but hides complexity that burns experienced devs when things break.

It's a good article, made me stop and reflect, I remember early on there use to be limits to the depth of stacking but I have some doozies where parameters needed to be added layer 1 to make something work layer 20.

But to tear down a factory or to revolt against a government or to avoid repair of a motorcycle because it is a system is to attack effects rather than causes; and as long as the attack is upon effects only, no change is possible.

I’ve been told a few times recently my 10+ year-old code was moved to S/4HANA Cloud. I feel BAL logging is half the reason it survived

Agree writing is such an underestimated skill, the more you flex it the better you get

Wait till he works out that he will have to deploy his app on every instance and then work out Cloud Logging already has these metrics and more and works with multi instances out of the box

BTP Ctms has a feature where you can tag transports, interested in how people using to correlate say a Jira ticket with a Cloud ALM feature ID so when an issue downstream can find the source easily

Cool, I saw you can use tags in TMS. Does SAP CI/CD allow pushing Git tags to TMS, for example linking to a Jira or SNOW ticket?

Used to a separate CI server. Curious where Git workflow starts and ends in SAP CI/CD. Local tests, PR, builds, deploys. How is it all structured?

John Patterson @jasper07.secondphase.com.au · 4d

Curious about the workflow, local tests run before GitHub Actions, then a PR? Where does the build happen, and does CI/CD run on push or only PR approval?

John Patterson @jasper07.secondphase.com.au · 4d

Interesting, so sharding fails in SAP CI/CD because cds test only runs one CAP instance, one DB, one global cds env, and you can’t glob tests to create own shards cc @mauriciolauffer.bsky.social we talking one Unit, integration, and E2E? No Docker per shard || concern possible?

I have a similar draft on intentional moduliths using DDD, organizing your app into clear, domain-aligned modules that communicate via event-driven interactions. Improving maintainability, testing, and modularity while deploying as one unit, easing future microservice transition.

The last chapter - Cloud and Services

From transactions to partitions, replication, consensus, and durable execution.

The author closes with stories from his 10 years at SAP, on how cloud provisioning changed how he worked.

Reading "Think Distributed Systems"

Like no other book I've read. Builds mental models - start with basics then layer on. How transactions work, distributed transactions, durable execution

Concise definition, how to think about it. Each builds on prior

Magical systems thinking - Works in Progress Magazine

Systems thinking promises to give us a toolkit to design complex systems that work from the ground up. It fails because it ignores that systems fight back.
