  • mod-circulation-19.0.9
  • mod-circulation-storage-12.0.1
  • okapi-3.1.1

Environment:

  • 55 back-end modules deployed in 110 ECS services
  • 3 okapi ECS services
  • 8 m5.large  EC2 instances
  • 2 (1 reader, 1 writer) db.r5.xlarge AWS RDS instance
  • INFO logging level

  2. Below is the dependency graph generated from Giraffe for single POST_/circulation/renew-by-barcode API. It shows individual calls made by renew-by-barcode to gather prerequisite data from different APIs such as item-storage, location-units, loan-types, request-storage, notice-policy, locations, and mod-authtoken. In all, this call took 990 ms, and 6% of that is consumed by mod-authtoken and the remaining 94% of the time is taken by other APIs to gather prerequisite data.
