  • qlever index now monitors memory usage of the index-building process in the background and logs peak memory at the end.
  • After indexing completes, a qlever.<dataset>.memory-log.json file is written to the working directory with timestamped RSS samples and peak usage.
  • Works in both native mode (via psutil) and containerized mode (via docker stats / podman stats).
  • As other graph databases are integrated into qlever-control, each engine's indexing will produce its own memory log in the same format. These can be compared side-by-side using the evaluation web app to visualize memory usage differences across engines and datasets.
