-----------------------------------------
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}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)
