Query: Fast Failure Recovery for Main-Memory DBMSs on Multicores   Main-memory database management systems (DBMS) can achieve excellent
performance when processing massive volume of on-line transactions on modern
multi-core machines. But existing durability schemes, namely, tuple-level and
transaction-level logging-and-recovery mechanisms, either degrade the
performance of transaction processing or slow down the process of failure
recovery. In this paper, we show that, by exploiting application semantics, it
is possible to achieve speedy failure recovery without introducing any costly
logging overhead to the execution of concurrent transactions. We propose
PACMAN, a parallel database recovery mechanism that is specifically designed
for lightweight, coarse-grained transaction-level logging. PACMAN leverages a
combination of static and dynamic analyses to parallelize the log recovery: at
compile time, PACMAN decomposes stored procedures by carefully analyzing
dependencies within and across programs; at recovery time, PACMAN exploits the
availability of the runtime parameter values to attain an execution schedule
with a high degree of parallelism. As such, recovery performance is remarkably
increased. We evaluated PACMAN in a fully-fledged main-memory DBMS running on a
40-core machine. Compared to several state-of-the-art database recovery
mechanisms, PACMAN can significantly reduce recovery time without compromising
the efficiency of transaction processing.
