Abstract

After MP consumer MVP is deployed to production, we noticed that MP consumer have high memory usage between 1.5GB and 3GB, which gradually grows but never shrink.

After the investigation, we find out some root causes and propose some solutions.

Experiments

We run the following experiments to reproduce the issue and try to identify the root cause.
