- Comparing kafka.m5.2xlarge against kafka.m7g.2xlarge instance type
- The main KPI for the workflows do not differ significantly (Data Import durations and CI/CO response time do not differ significantly. The number of requests in ). During 2 hour CI/CO with Data Import tests the number of requests were similar for both MSK clusters- 287669 in m5 and 287155 in m7g MSK instance type. Duration of data import update job with 25k records is longer for 2 minutes with m7g instance type.
- MSK resources utilization. CPU decreased slowly (1% - 6%) with m7g instance type. Memory usage is on the same level.
- Resource utilization
- Memory utilization didn't differ a lot between two MSK clusters
- Average DB CPU utilization is 85% during create jobs and 87% during update jobs for tests with different MSK instance types. DB CPU utilized 15% during Check-In/Check-Out period without DI.
- Average connection count is about 850 connections for create and update jobs with CI/CO and 730 connections for CI/CO without data import for tests with different MSK instance types.
- MSK instance CPU and Disk utilization is similar in both kafka.m7g.2xlarge and kafka.m5.2xlarge.
- Deltas for CPU utilization shows in mod-di-converter-storage-b 20% decrease for update job and 10% decrease for mod-feesfines-b module. The rest modules CPU utilization deltas fluctuate under 10%.
