-----------------------------
Summary: Memory leak of DataStreamMapImpl when Streaming write
Key: RATIS-2213
URL: https://issues.apache.org/jira/browse/RATIS-2213
Project: Ratis
Issue Type: Bug
Components: Streaming
Reporter: ChenXi
Attachments: image-2024-12-17-16-44-13-020.png
h2. Phenomenon
During our online test of Streaming writing, we found some memory leaks. When a
DN write traffic exceeds 1GB/s ~ 2GB/s, Netty's Direct memory will continue to
grow.
h2. Version
Ozone-1.4.1 based internal build, use the Ratis version 3.1.1
h2. Reproduce Way
I found two ways to reproduce the DataStreamMapImpl#
map and DataStreamManagement#streams leaks.
For the detail we can refer to https://issues.apache.org/jira/browse/HDDS-11939
