M.S. Paper Title: MitMem: Mitigating Millisecond Tail Latency with
Fast-Rejecting GC-Aware Mechanism

Abstract:
An increasing number of high-performance distributed systems are
executed on top of runtime environments like Java Runtime Environment
(JRE), such as Cassandra [41], Hadoop [53], Spark [60], Hazelcast
[10], Alluxio [1], Hive [56], and RethinkDB [13]. The developers are
attracted to a managed language like Java as it offers services like
Garbage Collection (GC), run-time type checking, reference checking,
and cross-platform execution. However, many applications running on
the JVM (e.g., big data frameworks such as Hadoop, data stores such as
Cassandra) suffer from long garbage collection (GC) time. The long
pause time due to Stop-The-World (STW) during Garbage-Collection (GC)
not only degrades application throughput and causes long latency, but
also hurts overall system efficiency and scalability. To address these
problems, we implement MITMEM that provides JVM support to cut
millisecond-level tail latencies induced by GC. MitMem is a JVM
drop-in replacement, requires no configuration and can run
off-the-shelf Java applications with a minimum modification (e.g.,
adding 120 LOC to integrate with Cassandra). Our experiments indicate
that the MITMEM-powered Cassandra successfully reduces the tail
latency up to 99%.

Daniar's advisor is Prof. Haryadi Gunawi
