krakendio / krakend-httpcache Goto Github PK

Hey, I'm wondering if it would be possible to support overwriting the cache lifetime in the config.

My usecase specifically is a very short cache (~30s or so) to keep the load on the backends low. However, I do not want to set this as the Cache-Control header on the backend (particularly because I don't have control over all backends).

I don't have any knowledge of Go at all so I can't really do a PR right now.

Hi guys,

Hope you are all well again !

How would you integrate an api proxy like sourcegraph's apiproxy to manage MaxAge revalidation values per krakend routes in the config file ?

And, I extend my question with other cache storage backends as you can use several with gregjones' package. (https://github.com/gregjones/httpcache#cache-backends). So how can I extend krakend-httpcache plugin to manage specific configs for local or cloud backends like redis, badger or azurestorage.

httpcache storage configs examples:

• Local/Badger https://github.com/sniperkit/cache/blob/sniperkit/backend/local/badger/handler.go#L49-L103
• Local/BoltDB https://github.com/sniperkit/cache/blob/sniperkit/backend/local/boltdb/handler.go#L47-L51
• Cloud/GCS: https://github.com/sniperkit/cache/blob/sniperkit/backend/cloud/gcs/config.go#L11-L23
• Cloud/AzureStorage: https://github.com/sniperkit/cache/blob/sniperkit/backend/cloud/azurestorage/config.go#L11-L16

The idea is to gain some flexibity on caching content from rate limited api providers, like github.com,..., and to gain manage it from the config file. Use case: integration of krakend with flogo and the flogo webui.

Cheers,

i am trying to cache from backend which returns header as Cache-Control: no-cache, no-store, max-age=0, must-revalidate
. is it possible to cache data in this scenario and want to cache for 1 minutes max? let me know your suggestion

HI,

i'm currently reading the documentation of KrakenD and I'm a bit surprise about this httpcache feature :

• indeed, this is really simple...
• but it depends on github.com/gregjones/httpcache and the project is archived

Is it the same for the entreprise version ?

Hi there!

Krakend's doc states that the admin is responsible of the amount of RAM dedicated to the memory cache (no way to specify a maximum amount, LRU eviction, etc.

Also, this implementation does not make use of shared cache topologies in multinode deployments (with more than one krakend running)

It's strange there is no support to Redis or memcached services. I see you use https://github.com/gregjones/httpcache so it's a pity you can't use at least the https://github.com/gregjones/httpcache/tree/master/memcache version which would allow for a shared memcached server.
