Abstract:
In a data-shipping database system, data
items are retrieved from the server machines,
cached and processed at the client machines, and
then shipped back to the server. Cache consistency
controls typically rely on a centralized server or
servers to enforce the necessary concurrency
control. This system presents a consistency control
protocol, Active Data-aware Cache Consistency
(ADCC) that allows clients to be aware of the
global state of their cached data via a two-tier
directory.In addition, ADCC performs the
concurrency control from the server to the clients.
