Agree with @szetszwo. At present the writing flow of Ozone streaming has working. And our client also had avoided buffer copy.(Although we are currently using star Topology). I think we can do a simple performance test now. Currently our implementation is very simple, which makes it easier to locate performance issues. We need to address performance issues first. @bshashikant In addition, I will test the performance of streaming with checksum enabled and without checksum enabled. To verify checksum's impact on performance. (The default value of io.bytes.per.checksum in HDFS is 512 bytes)Perhaps checksum's performance overhead isn't that high. Let's make sure by testing it first. -- This is an automated message from the Apache Git Service.
