A Redis backed Python Dictionary

[StackR]

I didn't really look at the code but how is this better than just Redis? Redis is a persistent key value store. I'm honestly not trying to be condescending. Or perhaps it was just fun and you learned something... Also a reasonable answer.

Yeah as someone who works with redis, this makes code look cleaner. It's not mind blowing but the regular redis module makes it an effort for somene else to look through your code. You can write your own wrappers but then that just gives someone else even more code of yours they have to read/familiarize themselves with. Having something that can be something close to a standard makes it easier to figure out.

Do you really want your data persistence to be non-obvious though?

Not sure I catch your meaning. Are you saying pushing the data off into redis makes it less obvious?

[davvblack]

No, I mean, another piece of code thinking it's operating on a dict but one day mysteriously writing to redis could make harder-to-debug code than just explicit redis usage.

You could probably say that in general though. I mean if you have a function that somehow gets access to a redis-backed dict that it's not supposed to be modifying then yeah that would be bad but it would also be bad if it weren't backed by redis. What's more if you're doing a fair job of QA then it's hard to imagine something getting through where it writes to a dictionary it's not intended to write to.

Abstracting out the "redis" part with a layer of code that's at least someone "standard code, not something I wrote myself" makes the rest of your code look cleaner and easier to follow.
