----------------------------------
Summary: Adapt BackPressureStatsTracker to work with credit-based
flow control
Key: FLINK-9014
URL: https://issues.apache.org/jira/browse/FLINK-9014
Project: Flink
Issue Type: Sub-task
Components: Network, Webfrontend
Affects Versions: 1.5.0, 1.6.0
Reporter: Nico Kruber
Fix For: 1.5.0, 1.6.0
The {{BackPressureStatsTracker}} relies on sampling threads being blocked in
{{LocalBufferPool#requestBufferBuilderBlocking}} to indicate backpressure but
with credit-based flow control, we are also back-pressured if we did not get
any credits (yet).
