Abstract
Emerging non-volatile memory technologies (NVM) offer fast and byte-addressable access, allowing to rethink the durability mechanisms of in-memory databases. Hyrise-NV is a database storage engine that maintains table and index structures on NVM. Our architecture updates the database state and index structures transactionally consistent on NVM using multi-version data structures, allowing to instantly recover data-bases independent of their size. In this paper, we demonstrate the instant restart capabilities of Hyrise-NV, storing all data on non-volatile memory. Recovering a dataset of size 92.2 GB takes about 53 seconds using our log-based approach, whereas Hyrise-NV recovers in under one second.
