-----------------------------------------
Summary: Buffer debloating microbenchmark for single gate
Key: FLINK-24230
URL: https://issues.apache.org/jira/browse/FLINK-24230
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Affects Versions: 1.14.0
Reporter: Anton Kalashnikov
Fix For: 1.15.0
Currently, there are no microbenchmarks that check buffer debloating
effectiveness. The idea is to create one which will measure the checkpoint
time. The benchmark should be similar to `UnalignedCheckpointTimeBenchmark`
but unlike the `UnalignedCheckpointTimeBenchmark` where we see the effect of
`Buffer debloat` only for extremely small values like 1ms for
BUFFER_DEBLOAT_TARGET. This benchmark should provide a more reliable way to
check the different implementations of `Buffer debloat` it can be reached by
increasing at least record size and checkpoint interval. The main target is to
have how long will it take to do the checkpoint during backpressure when all
buffers are full.
