The SAND project explores
highly-distributed query processing for large-scale peer-to-peer
systems, federated enterprise databases, and wide-area monitoring
systems. A key focus area is network awareness, i.e., the use of the
knowledge of network characteristics such as bandwidth and
inter-node latencies, in query processing. Current topics include
query placement, parallelized execution, and adaptivity to changing
workload and network conditions.
Our
VLDB'04 paper
explores the benefits of network-awareness in operator placement for
data stream processing in a wide-area network setting. In a follow-up
paper,
we provide experimental results (using Borealis deployed on
PlanetLab) demonstrating the benefits of network-aware query
processing. Our
NetDB'05 paper studies the question of scalable, low-latency execution of joins in networked environments.
