NHibernate and Memcached - Tutorial/Example

Question

I have the Membase server installed with a couple buckets setup and I was looking for a good tutorial or example of how to use this as the 2nd level cache with NHibernate.

Answer 1

In your mapping files, you will need to include the property:

Options are read-write (read committed isolation), nonstrict-read-write (objects that are rarely written, better performance but increased chance of stale data), or read-only (data that never changes).

Then, in your web (or app) config you need a section to configure memcached:

Finally, in your session factory configuration be sure to use:

  
    
      

      300 
      NHibernate.Caches.MemCache.MemCacheProvider,NHibernate.Caches.MemCache
      true
      false 
    
  

Of course you will need to download and reference a dll from the appropriate version of NHibernate.Caches to get the right cache provider. The memcached one takes a dependency on ICSharpCode.SharpZipLib and Memcached.ClientLibrary as well (s/b included in the download)

If you're using fluent NHibernate, there is a .Cache method in the setup chain for a session factory that you can use, though some of the properties need to be set manually through a call to .ExposeConfiguration.
