Transaction reconstruction

Databases are distributed and replicated to increase the efficiency and resiliency of a database management system; unfortunately, mechanisms to improve resiliency can have a substantial negative impact on the overall efficiency of the system. Current approaches to resiliency extend transaction execution to include multiple copies of entire (or key portions of) transactions to increase the likelihood that transactions survive intervening failures, adding substantial overhead to the system in anticipation of failures that may or may not occur. My research introduces a new, optimistic approach to fault tolerance: reconstructing transactions interrupted by failures. Reconstruction duplicates only those components of active transactions that are actually lost when failures occur, offering superior efficiency while retaining a level of resiliency comparable to that achieved by replication.
