New comment by macca321 in "Fine-grained caching strategies of dynamic queries"

macca321 — Thu, 21 Sep 2023 08:23:34 +0000

About 15 years ago I implemented "cache namespacing" for memcached, where you build a final cache key for a stored item (e.g. "profile_page") by doing an initial multiget cache query for all the "namespace" version values (e.g "user_123", "team_456" might be needed for "profile_page"), which you combine together as a prefix for the final cache key.

You can then invalidate any final cache key that uses one of the namespaces by incrementing the namespace key.

I haven't come across this technique mentioned elsewhere since, but it's very useful.

See the namespaces section in the now 404ing memcached FAQ https://web.archive.org/web/20090227062915/http://code.googl...

I guess nosql, edge caching and materialised views make it less applicable than it used to be (when inelastically scaling single/replicated SQL instances were the only game in town and taking load off them was vital).

Or is this technique now a first class feature of various cache client SDKs?

It'd be very interesting to know Hashi's internal strategy around this.

- Maybe do nothing, and as long as OpenTofu doesn't attempt to extend Terraform they are in not that different a position than pre-MPL.

- Add so many features OpenTofu can't keep up?

- Add some sneaky code to latest versions of hashi providers which makes them not work with unofficial terraform binaries?

You can exfiltrate secrets that aren't in the state, but are in accessible resources during a plan using an http data source with the secret encoded into the url

I wonder if a non commercial Terraform Cloud "offering" like https://github.com/leg100/otf is "competing" with Hashicorp...

In the long run, I wonder if all video will be signed via blockchain-or-other-trusted-3rd-party. You'd need everything from the camera to the the editing software to support it though.

I would really like a client-side js library that lets you sync localstorage to consumer cloud storage (onedrive/gdrive etc)

The thing people like about Facebook is looking at other peoples photos, safe in the knowledge that they don't know you are looking at their photos.

It would be a lot harder in the Culture to get someone to be your human footstool.

I think a process like this works well for enabling the success of the kind of people who like the sound of a process like this.

In a polyglot shop, it can actually be quite handy that HCL is it's own relatively simple language.

Better to return a union of custom result types. Save exceptions for when stuff goes really wrong.

I don't like it either, but one advantage is that the settings can be live updated when the config files change
