Work Description: mxm opened a new pull request #11478:
URL: https://github.com/apache/beam/pull/11478
The BufferingDoFnRunner create a new state cell for buffering data during
each
checkpoint. This led to the number of state cells to reach Short.MAX_VALUE,
the
maximum of supported Flink states.
This change keeps a fixed number of state cells depending on the maximum
configured parallelism for checkpoints. The state cells are reused after the
checkpoint has been acknowledged.
