--------------------------------
Summary: Possbile OOM in KBinsDiscretizer
Key: FLINK-31625
URL: https://issues.apache.org/jira/browse/FLINK-31625
Project: Flink
Issue Type: Bug
Components: Library / Machine Learning
Reporter: Fan Hong
In KBinsDiscretizer, the main computation `findBinEdgesWithXXXStrategy` is put
into a single subtask. While data sampling is used to decrease memory usage,
the memory overhead can still be prohibitive for large input vectors,
potentially resulting in OOM errors.
A potential solution is to implement parallel computation, distributing the
data evenly among all workers.
