nice :)
We recently used the current ehcache based implementation on a site
with an high traffic (> 1M page view/day) and very dinamic pages,
tweaking it in order to cache all the most accessed documents in
memory for a short timeframe, and this worked very very well...
anyway, we also was facing some limitations due to the legacy cache
module implementation and started to think about a few
enhancement/modifications.
I still haven't check your code but there are a couple of thoughts
that I think I could work at:
- different compression methods: we currently only support gzip, but
we should be able to apply different compression methods and maybe to
chain them. We added a javascript compression based on Dojo ShrinkSafe
that gives a real boost to ajax-intensive websites, I think this could
be added by default to the cache module (we also tested a css
compressor that can be added, although it didn't looked so useful as
the javascript compressor).
Good idea - had not thought about this - although given the
following, it should be very easy:
- decouple compression from caching: actually we can gzip only content
that it's cached.
Done - it's a separate filter now :)
But what about gzipping content (e.g. css) without
caching it?
info.magnolia.module.cache.filter.StandaloneGZipFilter :)
Or reuse the same compression with different cache
implementations?
You can have multiple cache configurations, and multiple instance of
the cache filter, each refering to its own cache configuration by name.
- ability to configure cache regions: e.g. pages that need to be
cached for a long time in filesystem and resources that needs to be
kept in memory.
As above - multiple cache configs are possible.
It would be nice if a new cache module implementation could be ready
for those features (at least providing a way to plug them in)... did
you had any similar requirement/thought? Do anybody have any objection
if I start pushing those things in? :)
Please check what's in now - and let's discuss before starting more
work - I don't consider the api stable or finalized just yet.
One thing that'd interest me specifically is some feedback on your
ehcache configuration tweaks, and how it behaved with large documents.
Cheers,
