Overview

This document contains the results of testing workflows Check-in/Check-out and Data Import for MARC Bibliographic records in the Quesnelia release with a new MSK instance type where zookeeper instances are not required. The main idea is to see how the kafka.m7g.2xlarge with KRaft mode affects FOLIO performance. Compared results for main workflows with different instance types: kafka.m5.2xlarge against kafka.m7g.2xlarge.

Ticket: PERF-936 - Getting issue details... STATUS

Summary

  • Comparing kafka.m5.2xlarge, zookeeper metadata mode against kafka.m7g.2xlarge, KRaft metadata mode
    • Tests with KRaft mode enabled utilize less CPU resources by brokers ((5% at least, for some broker - 13%) during CI/CO and during DI + CI/CO and at the same time the CPU utilizations are more balanced across the brokers compared to zookeeper mode
    • Main workflows KPIs do not degrade in tests with Check-in/Check-out with Data import
    • No memory leaks. No errors during tests.
  • Resource utilization
    • Service memory usage doesn't differ in tests with both MSK cluster
    • Service CPU utilization in Zookeeper mode: mod-inventory-b - 147%, mod-quick-marc-b - 81%, mod-di-converter-storage-b - 116%, nginx-okapi - 79% the rest of modules utilized less than 50%
    • Service CPU utilization in KRaft mode: mod-inventory-b - 133%, mod-quick-marc-b - 75%, mod-di-converter-storage-b - 103%, nginx-okapi - 75% the rest of modules utilized less than 50%
    • DB CPU was on level of 90% during tests with both MSK cluster

DB Connections

Average connection count is about 900 connections for create and 860 connections for update jobs with CI/CO. 770 connections for CI/CO without data import for tests with different MSK instance types.

MSK resource utilization (CPU)

  • Tests with KRaft mode enabled utilize less CPU resources during CI/CO and during DI + CI/CO and the same time it is more balanced compared to zookeeper mode
  • The difference is 5% at least. For some brokers the difference is 13%.

Methodology/Approach

  • Populate ptf-mobius-testing2 cluster with topics from tenant cluster
  • Run CICO for 2 hours
  • After 10 min delay after start of CICO Run DI Create - Export - Update for 5 and 25k
  • Run alone Data Imports
  • Create new kafka cluster
  • Populate NEW cluster with topics from tenant cluster
  • Run CICO for 2 hours
  • After 10 min delay after start of CICO Run DI Create - Export - Update for 5 and 25k
  • Run alone Data Imports
  • Compare resource utilization of MSK and main KPI for CICO & DI
