Query: Multi-Tier Buffer Management and Storage System Design for Non-Volatile
  Memory   The design of the buffer manager in database management systems (DBMSs) is
influenced by the performance characteristics of volatile memory (DRAM) and
non-volatile storage (e.g., SSD). The key design assumptions have been that the
data must be migrated to DRAM for the DBMS to operate on it and that storage is
orders of magnitude slower than DRAM. But the arrival of new non-volatile
memory (NVM) technologies that are nearly as fast as DRAM invalidates these
previous assumptions. This paper presents techniques for managing and designing
a multi-tier storage hierarchy comprising of DRAM, NVM, and SSD. Our main
technical contributions are a multi-tier buffer manager and a storage system
designer that leverage the characteristics of NVM. We propose a set of
optimizations for maximizing the utility of data migration between different
devices in the storage hierarchy. We demonstrate that these optimizations have
to be tailored based on device and workload characteristics. Given this, we
present a technique for adapting these optimizations to achieve a near-optimal
buffer management policy for an arbitrary workload and storage hierarchy
without requiring any manual tuning. We finally present a recommendation system
for designing a multi-tier storage hierarchy for a target workload and system
cost budget. Our results show that the NVM-aware buffer manager and storage
system designer improve throughput and reduce system cost across different
transaction and analytical processing workloads.
