Changed

  • Fetch pipeline performance overhaul — resolves production DB overload on small servers (2-core/4GB) where 569 fetch jobs backed up and PostgreSQL hit 150% CPU
    • Normalize GUIDs to lowercase on write, replacing LOWER(guid) queries that forced sequential scans — existing btree indexes now used correctly
    • Restructure advisory lock in FetchRunner into 3 phases (lock/fetch/write) so DB connections are not held idle during HTTP requests
    • Add BatchItemCreator for bulk item lookups — reduces per-fetch queries from ~N*2 to 2 regardless of entry count
