Hello, I had a few items I've been taking for granted and I was wondering if anyone could clear up for me. First of all, I did some searching and I realize Google employees can't say exactly where the servers are. However, one issue that affects me is I've been counting on performance being equal among European and American users. I assumed that if an American user logs on, they will be talking to an American server serving my application and if a European user logs on, they'll be talking to a European server. Is this the case? If so, if I have American and European users intermingling in a live environment, is my application a good candidate for HR? Perhaps I don't fully understand the Master Slave/HR distinction and someone could shed some light upon this.
Additionally, I realize that I shouldn't be using memcache for storage I can count on without writing to the datastore. I've read that "even within a minute" the key can be evicted. However, what about within say 3-5 seconds? Could I count on a key being written in the memcache and not being evicted within such a small timeframe with high confidence? Perhaps another question in the same vein would be, what is the average key life when the memcache is under pressure?
