Linq – Does anyone know of anyone working on a LINQ-to-Memcached provider

cachinglinqmemcached

As title. I didn't find one via google, at any rate.

Update: thanks for the links from the two answers; this is very useful, but not what I was after – I am curious to see whether it is possible to query an IRepository backed by memcached (or some other distributed cache), backed by a RDBMS. I've really no idea how that might work in practise; I don't know very much about the internals of either distributed caches or LINQ providers.

I'm maybe envisaging something like the cache LINQ provider generating cache-keys based on the query automatically (where query could be Expression> or some kind of Specification pattern implementation), and basically can be plumped down inbetween my app and my DB. Does that sound useful?

If you don't mind throwing NHibernate between them, you can use LINQ to NHibernate to query entities which can be set to use memcached as their cache.

How to know if memcached is doing anything

I know this question is old, but here is another useful approach for testing memcached with django:

As @Jacob mentioned, you can start memcached in very verbose mode (not as a daemon):

memcached -vv

To test your django cache config, you can use the low-level cache api.

First, start up the python interpreter and load your django project settings:
```
python manage.py shell
```
From the shell, you can use the low-level cache api to test your memcache server:
```
from django.core.cache import cache
cache.set('test', 'test value')
```

If your cache configuration is correct, you should see output in memcache similar to this:

<32 set :1:test 0 300 10
>32 STORED

.net – LINQ to XML – How does it work

LINQ to XML is really just LINQ-to-Objects, that work on objects representing XML. So when you write a LINQ query to retrieve nodes from an XDocument (for example), you are actually just invoking extension methods that returns IEnumerable<T>'s, and invoking the standard query operators as they are defined for IEnumerable<T>.

So, one could say that LINQ-to-XML mostly consists of the XElement family of XML-representing classes and the many extension methods that are provided for those, in order to make queries easier.

This is also explained here.
