Prices have never been cheaper and yet deletion strategies remain important. The flaw in this assumption is twofold - data creation grows faster than the price

Prices have never been cheaper and yet deletion strategies remain important. The flaw in this assumption is twofold - data creation grows faster than the price drops and “garbage” data can have performance implications. Cloud storage providers love it if you never delete data because they’re charging you more than it costs, but internally they need to carefully and speedily delete data you’ve asked them to delete because it’s a cost (you’re not getting billed for it).
- sitkack 3y agoI don't disagree, but this doesn't address that "if it were free" design point. Obviously retrieval isn't free, and we have only so much write bandwidth. But a GC might be able to use this in pretty neat ways. You could page out allocations that you think aren't going to be in use, or rarely in use. If you write it to storage, you don't have to be sure. Now that kinda gives you extra infinite memory (the GC dream), so you could do things like project the same data structure into multiple ways depending on how it is being accessed (AoS, SoA, projected subsets, columnar, etc). We should be thinking about how to have computers decide that deletion strategy for us.
- iambateman 3y agoWe had full daily backups of our application stretching back to 2017, totaling six terabytes of cloud storage. They got to the point where it cost $200/mo just so we could theoretically restore the application as it was on June 5, 2018. I think deletion strategies will always be relevant from a “staying organized” standpoint, as well as cost.

- phantom784 3y agoIf it's important, you don't want to just write it to a hard drive and chuck it in a closet.
- WalterBright 3y agoTrue. Get two drives. One you chuck in a closet, the other you store off site.
- Dylan16807 3y agoEven if you specifically want to keep it in cloud storage, cold storage tiers would cost $6/mo. This is not an example where you need to delete. If the value is zero, go ahead, but it's sustainable to keep that data around.
