Rui Fan created FLINK-33042: ------------------------------- Summary: Allow trigger flamegraph when task is initializing Key: FLINK-33042 URL: https://issues.apache.org/jira/browse/FLINK-33042 Project: Flink Issue Type: Improvement Components: Runtime / REST, Runtime / Web Frontend Reporter: Rui Fan Assignee: Rui Fan Attachments: image-2023-09-06-15-43-37-075.png
Currently, the flamegraph can be triggered when task is running. After FLINK-17012 and FLINK-22215, flink split the running to running and initializing. We should allow trigger flamegraph when task is initializing. For example, the initialization is very slow, we need to troubleshoot. Here is a stack example, task is rebuilding the rocksdb after the parallelism is changed. !image-2023-09-06-15-43-37-075.png! -- This message was sent by Atlassian Jira (v8.20.10#820010)
