Notes

  1. Lots of time spent processing responses from fedora

    1. Valkyrie Fedora adapter resource query cache: https://github.com/samvera/valkyrie/tree/resource_cache @Daniel Pierce

    2. In-memory cache of built object with fedora etag

    3. Subsequent requests will send etag to fedora and use cached object if not changed

    4. Fedora 5 container in Valkyrie spec tests not starting properly and not responding

    5. Over request cycle about 50% speedup

    6. Daniel will talk with Fedora and Valkyrie folks about moving this forward

  2. VisibilityCopyJob and InheritPermissionsJob have large overlap and take a long time to process

    1. Lots of time spent walking work membership

    2. Experiment to combine functions of long-running jobs for visibility copy to reduce Fedora requests (related to above ^^): https://github.com/samvera/hyrax/commit/c8eabd6f9361c2cbfe03fd674ea522c7bc04a80e

    3. Cuts processing time in about half for changing a work’s visibility

    4. Solr Indexer batch processor work by @Rob Kaufman similarly should help by reducing duplicate work being done by the system

      1. Might not speed things up by clock time but reduce system strain

  3. PRs needing reviews:

    1. UV upgrade

  4. Next Meeting: 7/30/2025
