Hello
1、 The Rocketmq send compress message when the message size bigger than 4*1024
，you choose JDK deflate algorithm and set default level is 5，I
feel puzzled at this level， why 5？ why not 4,，why not 3 .....，whether not lz4
replace defate？
2、In DefaultMessageStore#putMessage method :
long beginTime = this.getSystemClock().now();
PutMessageResult result = this.commitLog.putMessage(msg);
long eclipseTime = this.getSystemClock().now() - beginTime;
if (eclipseTime > 500) {
log.warn("putMessage not in lock eclipse time(ms)={}, bodyLength={}",
eclipseTime, msg.getBody().length);
}
eclipseTime ? what do u mean？
