Instant Recovery

  • My PhD research is in the field of logging and recovery for databases. Our project, Instant Recovery, proposes a technique that enables database systems to start processing new transactions shortly after crashes and media failures, performing the required "redo" and "undo" operations on demand.
  • This project is based on the Shore-MT storage manager.

Brackit: XQuery and MapReduce

  • I previously worked in (and still maintain) the Brackit project, whose scientific contribution is described here, and whose source code is released to the public here
  • My main contribution in Brackit was the development of an execution engine for MapReduce, similar to systems like Hive, Pig, and JAQL.
  • For details about this project, I recommend our ADBIS 2013 paper, as well as the article in the Datenbank-Spektrum journal, both linked below.
