Research direction
The report only provides a memory-summary image and the versions flink-cdc-2.4, Flink 1.17.1, and Hudi 0.14.0; no source file or test is named. Start by reproducing the JobManager metaspace usage and tracing which component allocates it, then determine whether the reported 200+ MB is expected or represents a fixable leak.
