-------------------------------------
Summary: Remove unnecessary synchronisation in RecordSerializer
Key: FLINK-8172
URL: https://issues.apache.org/jira/browse/FLINK-8172
Project: Flink
Issue Type: Improvement
Components: Network
Affects Versions: 1.3.2, 1.4.0
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.5.0
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).
