Hi,

I want to know that whether there is any possiblity for replicationg the  
data stored in memcache server among multiple memcache servers.

I have 5 memcache servers in different places.

I need to replicate the data stored in one memcache server to all the  
other servers also - redundancy.

So that if any server went completely down i can have all the memcache  
data in other servers too…

Thanks if any one help me in this.

Thanks & regards,

Barakath

Hi,

If you need replication/high availability for cached objects, I’d  
recommend  
you to examine Tokyo Tyrant and Tokyo Cabinet, as a replacement of  
Memcached. Tokyo Tyrant acts as a network interface for concurrent  
access to  
Tokyo Cabinet databases -your persistence layer-, implementing memcached  
protocol. Thus you don’t need to alter your memcached clients.

And you have ruby bindings for that 🙂

Hope it helps

Cheers  
Alex

This should be (and has often been) asked on the memcached list, but I  
will  
answer here.

No, there is no replication in memcached. Memcached is simply a cache,  
not a  
durable data store.
