High Average Active Sessions for few seconds multiple times during peak load due to delayed commit ok initiated

Hi,

I have RDS Aurora Cluster MySQL (1 Writer, 2 Readers r5.4xlarge). Recently I have found that average active sessions increases (for writer only) for few seconds due to delayed commit ok initiated. it looks like there is no performance impact on the webapp associated.

I dont see any specific slow query on RDS slow logs.

Let me know how can I gracefully solve this issue.

Following is the screenshot of performance insights

Note: My Backend application is laravel application, which uses Elasticache and Aurora as data store

Help will be appreciated
