Can I create multi hash table?

可以。You can get the same effect by just putting a prefix in front of 
the IDs. So instead of a key of "foo" for a product, you'd use 
"product:foo". We do this very successfully with a large number of 
different object types.

If you can't do that, then you can also run multiple memcached instances 
and fetch different object types from each instance. We actually do a 
bit of that as well; we modified our client code to look at the key and 
choose from separate lists of servers for certain object types. 
(Unfortunately due to some licensing ambiguities in the code we 
modified, we can't release those changes.)
