Re: Lock-free databases

>> What "lock-free" patterns did you look at ?<<

One of the more interesting one was logical concurrency. Univac was playing with it in the lab, but I do not think it ever came out in a product. It looked at the queued statements, and picked out subsets of statements that could run at the same without conflicts by looking at the predicates. If a statement is in the queue too long, its priority gets raised until it is serviced. Received on Sat Nov 05 2005 - 18:18:30 CST
