             Summary: Test the buffer debloating
                 Key: FLINK-23928
                 URL: https://issues.apache.org/jira/browse/FLINK-23928
             Project: Flink
          Issue Type: Sub-task
            Reporter: Anton Kalashnikov


# {color:#6a8759}Configure the buffer debloat by setting `taskmanager.network.memory.buffer-debloat.enabled` to true{color}
 # {color:#6a8759}Start the job with a long checkpoint time{color}
 # {color:#6a8759}Check the alignment time for each subtask it should be near taskmanager.network.memory.buffer-debloat.target{color}
 # {color:#6a8759}Check the checkpoint time it should be near taskCount * taskmanager.network.memory.buffer-debloat.target{color}
 # {color:#6a8759}Try to change taskmanager.network.memory.buffer-debloat.target. Checkponint time should be changed correspondetly.{color}
 # {color:#6a8759}Check metrics {color}{color:#6a8759}estimatedTimeToConsumerBuffersMs and {color}{color:#6a8759}debloatedBufferSize which also should depend on the current debloat configuration.

{color:#6a8759}Other configuration which can be changed for test.{color}
 * {color:#6a8759}taskmanager.memory.min-segment-size(if this would be equal to taskmanager.memory.segment-size then the behaviour should be same as with disabled buffer debloat)
{color}
 * {color:#6a8759}taskmanager.network.memory.buffer-debloat.period{color}
 * {color:#6a8759}taskmanager.network.memory.buffer-debloat.samples{color}
 * {color:#6a8759}taskmanager.network.memory.buffer-debloat.threshold-percentages{color}
