Review comment:
Let's recorded the forced position.

Review comment:
We should add one more method
```suggestion
default CompletableFuture<DataStreamReply> writeAsync(ByteBuffer buffer) {
return writeAsync(buffer, false);
}
CompletableFuture<DataStreamReply> writeAsync(ByteBuffer buffer, boolean
sync);
```
