ABSTRACT
Providing scalable database services is an essential require-
ment for extending many existing applications of the Cloud
platform. Due to the diversity of applications, database ser-
vices on the Cloud must support large-scale data analytical
jobs and high concurrent OLTP queries. Most existing work
focuses on some specific type of applications. To provide
an integrated framework, we are designing a new system,
epiC, as our solution to next-generation database systems.
In epiC, indexes play an important role in improving overall
