Hi all,
about caching in iBATIS, I've downloaded memcacheddonet library and I've find how someone can write an ICacheController as Ron's last post hereafter. But, my question is how can I, after writing MemcachedCacheController as Ron did, make iBATIS uses this controller instead of the default ones: LRU, MEMORY and FIFO. I've seen SqlMap.xsd it recognizes only LRU, MEMORY and FIFO. But, as I saw in that file, I could insert another cache implementation like MC for MemcachedCacheController . The problem is that somewhere it is asked to provide the implementation type as type alias, so where can someone tell iBATIS to use MemcachedCacheController ?
Thanks,
Tite

The ICacheController interface only has a few members to it. I didn't see anything in the MemcachedClient about removing multiple keys.
I haven't tested the code below but I'm able to run the MemcachedBench program against a win32 build of memcached:
http://jehiah.com/projects/memcached-win32/
I think the ICacheController should have a Shutdown member so 3rd party caches can clean up when the application shutsdown.
Of course all the properties on the pool object should be settable by
the properties argument. The properties argument should also have a key
to prefix items put into the cache so IBatisNet plays nice with other
programs using the cache. It should be possible to also integrate the FlushInterval construct into this implementation.
// untested - inspired by Memcached.MemcachedBench.MemcachedBench
public class MemcachedCacheController : ICacheController
{
private SockIOPool pool;
private MemcachedClient memcachedClient;
public object this[object key]
{
get { return memcachedClient.Get(Convert.ToString(key)); }
set { memcachedClient.Set(Convert.ToString(key), value); }
}
public object Remove(object key)
{
return memcachedClient.Delete(Convert.ToString(key));
}
public void Flush()
{
// empty
}
public void Configure(IDictionary properties)
{
string servers = Convert.ToString(properties["server"]);
pool = SockIOPool.GetInstance();
pool.SetServers(servers.Split(','));
pool.InitConnections = 3;
pool.MinConnections = 3;
pool.MaxConnections = 5;
pool.SocketConnectTimeout = 1000;
pool.SocketTimeout = 3000;
pool.MaintenanceSleep = 30;
pool.Failover = true;
pool.Nagle = false;
pool.Initialize();
memcachedClient = new MemcachedClient();
memcachedClient.EnableCompression = false;
}
}

I've done some fooling around with memcached... I still haven't looked into how to write a custom cache provider for ibatis though. If no one's done it by the time I get there, then I'll probably do it :)

Someone needs to write an IBatisNet cache client for memcached:

There is a closed source solution called NCache but its probably $$$.

Hi evry body,
I am new in using iBATIS as a data mapper in the project. But it works well. It allow me to have a better architecture of my application so it isolates correctly the data access. But my concern about it is distributed caching. Does iBATIS allows this kind of stuff or is there an open source solution that can be used with iBATIS like OSCache for iBATIS java?
