Perhaps the docs will improve soon - it is quite a new feature and they've only had 15 years to get it right after all. Besides, it's not like anyone really cares about data integrity 🤯

While I was at AWS, I heard many stories of painful disappointments in S3's multipart upload feature. Still wasn't prepared for how shockingly bad it is - the documentation is appalling.

Ready, set, build. Hello, world.

How did it take me so long to see these photos?! Grateful for a solid crew that day David - thanks for making the journey. Let's plan an even bigger adventure next time 😀

You mention the concept of a "consistent write" and to me this seems quite out of place. IMO, the property that is actually meaningful in context of an applied mutation is isolation.

Only if anyone was actually using on-demand and global tables at scale.

Spent the last 5 weeks back "home" in Australia 🇦🇺 Time with family and old friends, bird songs, eucalypt smells, swimming at beaches - all healthy food for the soul. Driving on the other side of the road, meat pie consumption, sampling local brews probably more of a health risk - but worth it.

Happy Australia Day!!

Coming years will be like one big long episode of a lousy reality TV show. Americans seem to be hooked on the drama.

Today is a good day to focus on remembering real American leaders and everything they stood for. I am a US citizen but these days, I'm pleased to "still call Australia home".

When my boat grows up she wants to be just like the Lindsey Foss.

etcd: getting 30% more write/s Undertaking performance analysis on our etcd clusters, I ended up with a 30% performance increase, and learnt lots about databases & disk…

One thing I see in this blog post is people running etcd on … EBS volumes, which of course introduced insane latency into fsync.

Perhaps the first step in dealing with etcd performance is sitting on an acceptable local SSD?

Agree that Snapshot Isolation is a sweet spot for application developers. It also enables practical time travel queries and debugging, which is challenging with lower isolation levels. I covered this topic in my blog post for my VLDB'23 paper: qianli.dev/blog/timetra...

Can't quite tell what you're talking about here.

Not unusual, but I would start raising questions now.

Just wow. Striped hound and me kinda wiped out by a Werner Hertzog documentary.

+1 for awk

I expect in time that DSQL will become a very good alternative to DDB for a great many use cases - now's a good time to experiment and share learnings!

Finally there are limitations which don't seem well defined yet. For example we know DSQL can have hot key contention on writes, but we don't know when to expect it. With DynamoDB we know it's 1000 writes/second for a given item up to 1KB in size.

DSQL is in preview and it could remain so for some time - the service has not yet had the level of production experience of DynamoDB and might have some wrinkles to iron out. I think also that there will be modeling best practices to map out - how to model for most consistent latency results.

Hi Luke - thanks for the shout out on my article - so glad you found some value in reading it. Your question about whether to choose DDB or DSQL is one that will be top of mind for many I think. IMO, for the moment DDB is still the steady and reliable production choice.

Dislike. "Good morning! Here is what I ate last night". Our dog has been having some sort of GI trouble of late - similar middle-of-the-night surprises.

Still way too expensive.

I don't actually think the price cuts on DDB are "big". Not expecting much, but hoping they'll have some actually meaningful announcements.

All good! Power was out for about 4hrs and had a tree limb fall across the driveway. Some suspicious pieces of roofing shingles in the yard that will need investigation.

National Weather Service says it might get “breezy”. Confirmed! November is often a string of storms - this is a little unusual to me because of the east winds - standard program is from the south. Power is out - could be a while.
