> Project: Flink
> Issue Type: Improvement

>
> While writing the records, RecordSerializer is the only owner of the `Buffer`
> into which data are written. Yet we are synchronisation twice per record
> while accessing MemorySegment. Removing this synchronisation speeds up the
> Network throughput in point to point benchmark by a factor of two (from
> ~12500records/ms up to 23000 records/ms).
