Welcome to the Chair for Decentralized Information Systems and Data Management!


  • Can your database system process one million out-of-memory TPC-C transactions per second? LeanStore can (VLDB 2023).
  • Are you still waiting for your data to load from S3? Better use BtrBlocks, our new columnar storage format for data lakes (SIGMOD 2023).
  • Project CODAC starts. The Cloud Analytics Benchmark, which will be presented at VLDB 2023, will serve as benchmark for the project.
  • LeanStore gets Snapshot Isolation. The paper (Scalable and Robust Snapshot Isolation for High-Performance Storage Engines) will be presented at VLDB 2023.
  • Let's co-design database and operating systems. The SIGMOD 2023 paper Virtual-Memory Assisted Buffer Management is the first step.
