Hi All,
I have one problem on Consistent Hashing in Memcached .
1. Virtual nodes. The usage of virtual node is to avoid the overloading,
here comes the problem , when I add a server to the memcached, there are two
things will do :
A. Steal some tokens from others
B. Allocate some new tokens
After these operations, the key's range is changed. How can we figure
this out? I knew there must be some data transfers during the it, how to do
it?Best Regards Tony Cui
