@kellabyte what about all the way through (ive seen also attempts) carbon emissions per transaction

Your SSD is a cache. S3 is the real database.

That sounds wrong until you see the math:

• S3: $0.023/GB/month
• EBS gp3: $0.08/GB/month
• 3x replication on EBS: $0.24/GB/month

At 10TB, that's $230 vs $2,400/month.

The trick is making S3 feel like local disk. That's what disaggregated storage engines do — hot path stays fast, cold path stays cheap.

The future of databases isn't faster disks. It's smarter caching on infinite storage.

The next challenging question is how to build a latency-sensitive OLTP database based on S3.

In case you are freaking out over using some mysterious asynchronous messaging library for #TypeScript, don't worry. It will feel exactly like async/await because it is async/await, but with all the benefits of the #ActorModel.

@DominikTornow recovery models pop up every decade, this time with a slight twist, model having a double meaning, welp

good to have handy when reviewing monitoring rules

@jorandirkgreef baseline as speed of light, understand the workload, a napkin calc with numbers every dev should know, bestbenchmark available hw, design the system and data structures to get the max out of available hw

@jorandirkgreef the world’s most reliable fsync ?

@jorandirkgreef removing unnecessary things from critical path

[Ruslan Rusu @ruslanrusu]

@VaughnVernon ah, that one

@DominikTornow analogy, to build high quality products you need manufacturing tools that are 10x more precise

This is what Ukraine's former nuclear shield looked like, which it gave up in exchange for security guarantees - for free, with nothing in return.

And now one of the "security guarantors" is waging a full-scale war against Ukraine, while the other is demanding that it hand over territory and natural resources in exchange for further "security guarantees".

Thank you america.
Thank you trump.
