Data/Storage Management The Group: John Kubiatowicz, Barbara Liskov, Scott Shenker Byung-Gong Chun, Alan Mislove, David Oppenheimer, Emil Sit, Hakim Weatherspoon
2
Applications The big thing about P2P: Management –Adaptation to failure –Self-Configuration Spectrum of Applications –Low Update, High Speed Reading –High Durability –Transactional applications Grand Challenges –Google-like high read performance –Internet Archive –Physics Applications –Amazon
3
What Semantics do we want from storage? Multiple Writers/ Multi-Object Transactions Performance –Caching Streaming –Effective event delivery –Effective update Delete Can we trust that data will still be there 10 years from now?
4
Open Question: Location control: –Is it important to place data? –Most “current apps” seem to desire control? –Most P2P solutions do not give control Implications of a layer of indirection –Is a layer of indirection important? –Is it fundamental?
5
Requirements for Real Storage Introduction Service –Who to speak to? –Are they the most current incarnation? Secure Routing: –Can we actually abstract away the routing Managed Infrastructure? –Much of our discussion seemed to assumed this –VS: Flakey Peer2Peer model
6
Desirable Services Management/diagnosis mechanisms Repair triggering facilities
7
Query the Data What types of queries should we support? –Efficient Joins vs –Data status and performance collection Reliability semantics –What happens under churn? Is this possibly universal? –Are there a set of querying mechanism that can be good for many apps?
