Abstract
Requirements on document engines include low query response time and
freshness of index data. Our solution to the problem is based on a DB
cluster consisting of PCs, each of them running an off-the-shelf
DBMS. The specialty of our approach is to allow concurrent execution
of insertion and retrieval on the same data. Our technique is based
on decomposing and parallelizing insertion and retrieval requests,
while at the same time guaranteeing correctness by an additional
high-level transaction manager. An important design decision with our
architecture is how to assign data to the different components, and
we compare several such alternatives. The speed-up obtained is
surprisingly good. The cluster-based architecture nicely defuses the
bottlenecks occurring with a single-component system.
