MODKBEKBJ-513 - Getting issue details... STATUS
Goal
Investigate the response time of GET /eholdings/packages/<packageId>/resources/costperuse endpoint.
Investigation
Endpoint's work steps:
- fetch title IDs from the holdings table;
- prepare requests to APIGEE
POST /uc/costperuse/titles. Limit up to 1000 title IDs per request. For publisher type = all - make 2 requests with parameter 'publisherPlatform' = true and 'publisherPlatform' = false - receive responses and generate mod-kb result

Response time comparison chart
The biggest part of time in table is waiting responses from APIGEE. Calculation and sorting on mod-kb-ebsco side takes miliseconds.
