Yes, it needs to be in 100 places, eventual consistency is all that matters.

Doubt any database systems would help. I am interested in algorithms, not off the shelf dbms, becaues I doubt they scale to 100 or 500 nodes... geographically distributed... It might seem like asking for a lot, but I am ready to accept eventual consistency. Received on Sun Apr 23 2006 - 15:07:57 CDT
