possibe to do layeredcache like https://github.com/karlseguin/ccache

layered cache for use for http caching like

Hm...so what do you propose exactly? 🤔

[hiqbn]

cache.Set("my-unique-key", "field",[]byte("value"))

entry, _ := cache.Get("my-unique-key","field)

cache.Del("my-unique-key")

[cristaloleg]

Forgive me, but I don't get it.
Basically we've a cache of...caches, am I get you correctly?

[hiqbn]

sort of cache of caches, more like redis hash functions hset, hget etc.

[hiqbn]

alternatively, how do we achieve the same thing with bigcache?

[cristaloleg]

1st solution I see:

<cache_name> + <key> : <value>

So basically you've a prefix for each key, which says 'where' this keys is present.

[hiqbn]

ok. thx

[hiqbn]

key + field = value

i can't clear all key fields with delete(key)
i would like to achieve hset / hget like redis with bigcache. how can i do this?

[cristaloleg]

Well, you can, you need to iterate over keys and check their prefix (see https://godoc.org/github.com/allegro/bigcache#BigCache.Iterator).
Yes, this is O(|number of keys|) but still a thing 😉

[hiqbn]

that's not very smart. can design one for layeredcache?

[hiqbn]

what other options do we have? smart / efficient way pls.

[cristaloleg]

I suspect that number of top layers is not very big, and it's also constant (with a high probability).
So making something like map[string]*bigcache.Bigcache will not hurt. Care to try?

[hiqbn]

sounds like a good idea. will implement when i have the time. i'm checking other options first.
