  • Data Export tests finished successfully on the Eureka environment using the "Default instances export job profile" and "srs - holdings and items job profile." Data Export tests were run on Central tenants.
  • During Test №1-2When comparing QECP1 Eureka with Quesnelia ECS, NON-ECS environments:
      • Data Export duration for the "Default instances export job profile" was almost the same across environments.
      • Data Export duration for the "srs - holdings and items job profile" showed a significant degradation: around 2.5 times longer for the 1k and 100k files, and around 5 times longer for the 500k file, and no clear reasons were identified.
  • During Tests №1 and №2, we noticed some background processes for Database, so we deactivated mod-fqm-managerdeactivated mod-fqm-manager. As a result, the repeated test showed a twofold improvement in performance.
  • Data Export jobs were getting stuck and returned a [401 Unauthorized] error with the message: "errors [{"type":"UnauthorizedException","code":"authorization_error","message":"Unauthorized"}]. To resolve this, we increased the token lifespan by modifying the KC_CONFIG_TTL parameter for mod-login-keycloak from 360s to 3600s and KC_ADMIN_TOKEN_TTL from 410s to 4100s:
      • {"name": "KC_CONFIG_TTL","value": "3600s"}
      • {"name": "KC_ADMIN_TOKEN_TTL", "value": "4100s"}

Test №1 - №2

Introduction: The Baseline QECP1 Environment configuration was applied, and CPU=0 was set for all modules.

Objective: The objective of these tests was to collect performance measurements for the data-export process across central tenant.

Results: During the test, we observed that the database was running a background process .  for Database, so we deactivated mod-fqm-manager. As a result, the repeated test showed a twofold improvement in performance.

Service CPU Utilization

Here we can see that mod-data-export used 28% CPU Instance Power in spike.
