Need help configuring Memcached to store values in MySQL Cluster I am working on a Memcached implementation with MySQL Cluster 7.2.
I have installed and configured memcached with following parameters: 

PORT="11211" 
USER="mysql" 
MAXCONN="1024" 
CACHESIZE="1024" 
OPTIONS="" 


but Memcached is working irrespective to the MySQL engine 
(i.e. when inserting to Memcached it is not storing into database)

Can any one help me out giving parameters so that it will access the ndb engine and store the values in both memcache and also in database?

I am not able to figure out the relation between the two.
The basic docs for using the Memcached API for MySQL Cluster 7.2 start at http://dev.mysql.com/doc/refman/5.5/en/mysql-cluster-ndbmemcache.html

On the memcached command line, you need to supply an option like "-E ndb_engine.so".  Memcached has a "pluggable engine" architecture, and the MySQL Cluster component is implemented as an NDB Engine.  When memcached starts up with the correct engine you should see a log message like this:
