Memcached-backed cache location? about nuster HOT 13 OPEN

If anything redis would be better considering it can store in both ram and disk

from nuster.

iiuc, ZeroMQ is a message queue, how can we find data by key in such system?

BTW, I'm working on using redis as 3rd backend store.

Hi, there's no plan to add support for memcached backed persistence, but the contribution is welcomed:)

Is redis compatible with the memcache-protocol? If so, one could use any stack as long as it is compliant, e.g. incl. couchbase.

@jiangwenyuan any pointers to the c-code you'd suggest studying in more detail?

@valentijnvenus Just out of curiosity, why do you need memcached-backed persistence?

Here's some code you might need to look into

https://github.com/jiangwenyuan/nuster/blob/master/include/nuster/nuster.h#L57 for parse nuster in global section

https://github.com/jiangwenyuan/nuster/blob/master/src/nuster/parser.c#L880 for parse nuster rule

https://github.com/jiangwenyuan/nuster/blob/master/src/nuster/cache/filter.c#L116 the entry of request/response, checking key existence

https://github.com/jiangwenyuan/nuster/blob/master/src/nuster/cache/filter.c#L290 caching data

etc

It would be good to have the ability to use Nuster in a cluster setup ie. replicate data to other nodes.
In my use case, I split the traffic 3 ways (for redundancy and load balancing) before it even hits Nuster, which dilutes the effectiveness of any caching

fwiw, I think something like ZeroMQ or NNG might be a better fit for this

oh ok, I was thinking the service would only be used to transfer content between running processes, not used as a backend.
maybe my misunderstanding of Nuster internals?

from nuster.

I see, do you mean use that as a sync mechanism?

from nuster.

yes, exactly

from nuster.

Interesting, thanks for the info:) I would evaluate that along with haproxy peers an other options.

Redis would be a better start in my opinion.

Interest worldwide - last 5 years - Memcached (blue), Redis (Red):

So if you want to start somewhere I would bet on the right horse 😄
