M.S. Paper Title: Toward Coordination-free and Reconfigurable Mixed
Concurrency Control

Abstract:
Recent studies show that mixing concurrency control protocols within a
single database can significantly outperform a single protocol.
However, prior projects to mix concurrency control either are limited
to specific pairs of protocols (e.g mixing two-phase locking (2PL) and
optimistic concurrency control (OCC)) or introduce extra concurrency
control overhead to guarantee their general applicability, which can
be a performance bottleneck. In addition, due to unknown and shifting
access patterns within a workload, candidate protocols should be
chosen dynamically in response to workload changes. This requires
changing candidate protocols online without having to stop the whole
system, which prior work does not fully address. To resolve these two
issues, we present CormCC, a general mixed concurrency control
framework with no coordination overhead across candidate protocols
while supporting the ability to change a protocol online with minimal
overhead. Based on this framework, we build a prototype main-memory
multi-core database to dynamically mix three popular protocols:
partition-based single-thread concurrency control protocol (PartCC),
OCC, and 2PL, and design a predictive model based on a set of simple
features to predict the ideal protocols for parts of workload. Our
experiments show CormCC has significantly higher throughput compared
with single protocols and state-of-the-art mixed concurrency control
approaches.
