distributed caching for .NET ?

[ask ksa]

hi,
is anybody familiar with production-ready distributed/clustered cache
solution for .net ?
Google helped me to found some (like ncache and
scale-out-state-server), but they are over-priced

thanks anyway for your time reading that

'Distributed' caching is a red-herring: you can't access a remote
object without some sort of remoting/services layer, which makes the
whole process rather 'slow' compared to utilizing caching features in
the RDBMS and re-loading the data: the data transfer protocols for for
example sqlserver are much more optimal than for example remoting or
webservices will ever be.

Add to that that you need security in your cache server, and you have
a 'solution' which isn't really bringing anything to the table.

Thanks for replay
sometimes you just need to save frequently -used some query results in
cache, that's all
in open-source word many solution exists for distributed caching :
memcached, EhCache and many more. they all solve existing problem
and most of scalable application utilize the use of clustered caching
(see the flickr architecture for example )

just wanted to hear about port for .Net
i agree with you that it always be more slow than database
but when you db run on 100% cpu, selective caching can solve the day
with no price

Thanks much

That argumentation assumes that:
1) the database server is as cost efficient to scale as the web servers
2) the cache product only support what they call "partioned" cache
not what they call "replicated" cache
3) there are no benefits for cache management by doing it in the
application that understands the data instead of in the database
4) there are no benefits from notification

#1 and #2 are not true.

#3 and #4 are not true in most cases.

MemCacheD is something I know has been used by some big sites and people
have been happy with. I would imagine it would run on Windows if you setup
CygWin. There's also a Windows port at:
http://jehiah.cz/projects/memcached-win32/

There's a .Net API for it at:
https://sourceforge.net/projects/memcacheddotnet/

That's a great explanation, clears up questions I had a couple years ago
concerning caching data in a singleton remote server.

Hello ask,

Read this http://www-128.ibm.com/developerworks/webservices/library/ws-soa-infoserv1/index.html?ca=drs-
and
http://www-128.ibm.com/developerworks/webservices/library/ws-soa-infoserv2/index.html?ca=drs-

This tho patterns (Data Federation and Data Consolidation) are the first
steps and the base of the Distributed Cache.
BTW, these whitepapers will give u some new patterns for the cache http://www.tangosol.com/white-papers.jsp

Also read my post there http://laflour.spaces.live.com/blog/cns!7575E2FFC19135B4!561.entry
about DataGrid (we discuss this point with Nick Malik - MS Enterprise Architect)

PS: Soon I'll post a UML diagram in my blog describiring the schema of distributed
cache

Thanks for reply, Chris
Memcached is really ready-to-go solution for linux,
the problem is that win32 port is buggy ( and the project home page
warning about not using it for production )
anyway, i gave a try for win32 memcached and fixed some bugs myself ,
but still, sometimes it is just crushes

I'll try CygWin , not familiar with it and i expect some problems (note
from CygWin homepage : "Cygwin is not a way to run native linux apps on
Windows. You have to rebuild your application from source if you want
it to run on Windows." ), but i still cant find good distributed cache
solution for .net

Thanks again
