> The following line in the BufferingSink on [this
> page|https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/datastream/fault-tolerance/state/#operator-state]
> has a bug:
> {code:java}
> if (bufferedElements.size() == threshold) {{code}
> It should be {{>=}} instead of {{==}} , because when restoring from a
> checkpoint during downscaling, the task may get more elements than the
> threshold.
