get all keys in cache about ccache HOT 10 CLOSED

the PR #35 would actually also make my life manageable :)

from ccache.

LayeredCache isn't otherwise convenient? (I could imagine a lot of cases where it isn't, just double checking).

If you specifically want a prefix delete, I think I'd like to add a DeletePrefix() method since we could do that a lot more efficiently (don't have to collect all the keys). Thoughts?

Hi,

I've looked at LayeredCache, but I'm sure how it could help me in that particular case, but maybe I'm missing something

Adding DeletePrefix() would be absolutely wonderful

I should have looked more into this before commenting. Only way to avoid collection is to hold a long-lived write lock on the bucket.

What do you think of this implementation:
356e164

I went for a shorter-lived write lock in exchange for more memory (collecting) and cpu (double iteration).

Doesn't support the onDelete callback right now, not sure if it should or not.

woh! that was fast :) For my very use case your implementation seems fine since I don't have millions of items and I prefer sucking a bit more on cpu rather than longer locking.

Let me give it a try on our product

from ccache.

I'll polish it up (documentation + merge) in the next couple days

from ccache.

Would it be possible to make that api DeletePrefixes(key ...string)? If i need to delete multiple prefixes, we would collect all the keys at once

from ccache.

I believe I can close my pr since this is a way more elegant way to achieve what we need. What do you think?

from ccache.

Sounds good :)

I just tried this patch in our app it works perfectly and I removed half of my code. I like that :)
