[GitHub] [flink] NicoK commented on issue #6417: [FLINK-9913][runtime] Improve output serialization only once in RecordWriter

I don't quite get the argument with the `pruneBuffer()` call having this much 
overhead...at least for small records since its implementation only prunes if 
the buffer is larger than 5MiB:
```
        public void pruneBuffer() {
                if (this.buffer.length > PRUNE_BUFFER_THRESHOLD) {
...
```
