Change subject: [KUDU-3447] Limit tablets copying speed ...................................................................... Patch Set 2: > Patch Set 1: > > (8 comments) > > Thank you for adding this. It would really help if you could add a little > more details about the following: > 1. I understand that you have mentioned about other services getting impacted > due to network jam caused by tablet copy operation, but that doesn't explain > why tablet copy operation would become a preferred bandwidth user over other > services. Is there an existing case where this kind of behaviour was seen and > what was making linux kernel to do that? > 2. Adding detailed information (in commit message) about the new library APIs > would be quite helpful for posterity. > 3. Limiting the network speed might cause frequent context switching. Do we > have any data on that from the performance point of view? About 1 and 2, please view: https://issues.apache.org/jira/browse/KUDU-3447 about 3, I will supplement some performance tests. -- To view, visit http://gerrit.cloudera.org:8080/19479 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I1f4834bfb0718a2b6b1d946975287a11f6be1fe3 Gerrit-Change-Number: 19479 Gerrit-PatchSet: 2 Gerrit-Owner: Wang Xixu <1450306...@qq.com> Gerrit-Reviewer: Ashwani Raina <ara...@cloudera.com> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Wang Xixu <1450306...@qq.com> Gerrit-Comment-Date: Thu, 09 Feb 2023 09:31:23 +0000 Gerrit-HasComments: No
