iamqq23ue opened a new issue, #4159:
URL: https://github.com/apache/rocketmq/issues/4159
version 4.9.1
From the ReputMessageService code, we can finally locate the following code。
“this.fileChannel.write(ByteBuffer.wrap(data));” is already possible to write
data to disk, why do we need FlushConsumeQueueService?
————————————————————————————————————————————
public boolean appendMessage(final byte[] data) {
int currentPos = this.wrotePosition.get();
if ((currentPos + data.length) <= this.fileSize) {
try {
this.fileChannel.position(currentPos);
this.fileChannel.write(ByteBuffer.wrap(data));
} catch (Throwable e) {
log.error("Error occurred when append message to mappedFile.",
e);
}
this.wrotePosition.addAndGet(data.length);
return true;
}
return false;
}
