Overview

This page is created to investigate Aurora serverless performance by comparing DB xlarge, 8xlarge and Aurora serverless instance types under load running Data Import (DI) with Check-in Check-out (CICO) running as background. 

Summary

  • The environment can handle the load with all compared DB instance types. 
  • No significant changes were observed comparing response times for CICO between two instance types db.r6g.xlarge and serverless. 
  • In Aurora serverless DI duration better for larger DI files.
  • Serverless v2 (32 - 128 ACUs) DB instance type configuration performs better from the start than (0.5 - 128 ACUs) due to increased capacity and its performance closer to 8xlarge. But to cut costs it's better to use (0.5 - 128 ACUs) for DB reader instance role. 
  • Aurora serverless RDS CPU didn't exceed 25% for any file size. Execution time or test duration has tendency to decreasing for bigger file size because of bigger ACUs.
  • Time duration of DI without CICO didn't change after task count: mod-inventory, mod-inventory-storage, mod-circulation, mod-circulation-storage x 4.

Results

The table includes test results from running on different database instance types Here we observe that RDS CPU utilization for db.r6g.xlarge has maximum values and test duration grows proportional to file size.

But after database was switched to Aurora serverless RDS CPU didn't exceed 25% for any file size. Execution time or test duration has tendency to decreasing for bigger file size because of bigger ACUs.

RDS CPU Utilization

RDS

CPU starts with spikes at the beginning of the tests and comes to normal after finish.


Test date: 2023-05-25

For xlarge database instance type CPU was maximum but it didn't affect DI any way. So it ran successfully 

Test date: 2023-05-29

For serverless CPU was stable and was not higher than 25%


Test date: 2023-05-30

Service

Data imports during CICO. The services worked stable and returned to there normal state after tests

CICO background process didn't affect DI and it worked as expected


Stable work of services


CICO resource consumption

Running tests for CICO PERF-593 - Getting issue details... STATUS I could observe that xlarge used more DB connections than any of DB instance types. The results mentioned in summary table show better response times over time for runs with 20 users. And no significant changes between different DB instance types. High latency was observed for all tests.

Response times for all DB configurations

Error rate correlates with DI file size - it grows with bigger files. The lowest error rate was with Serverless during 25 DI. All errors are in Check-Out Controller for POST_circulation/check-out-by-barcode (Submit_barcode_checkout)_POST_422.

For Aurora serverless it was observed response time growth instantly after DI start with smooth decreasing while executing (PTF - Create 2 job profile). 

For xlarge DB instance type CPU utilization during CICO stayed stable on level of 15% and after DI with 10k file rapidly go to 93% and stay on this level during all process of DI.
