I have a question about memcached distribution across nodes. We have 20 memcached nodes with 200GB memcached on each. Our apps are PHP apps.
What will be the result if the following things happen :
- Node 2 goes down
A key "XXX" which is on node 2 is asking to be setted
=> I suppose the key will be written on another node, maybe node 5
- Node 2 comes back up
- A try to get key "XXX".
Which node will memcached get the key from : node 5 or node 2 ?
