Yes, I ran this feature on our test cluster(3 nodes) with one writer(a separate server) and the target table has 365 tablets(hash, pre-replication). It seems that there was no significant increase in network traffic. But, i found a problem about the initial value for the "disk size". It's 365 * 8MB/tablet = 2.8GB even though the table is empty. -- To view, visit http://gerrit.cloudera.org:8080/13426 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I74406ab7cca7c22fda455c328b8ee9989a6b2d99 Gerrit-Change-Number: 13426 Gerrit-PatchSet: 31 Gerrit-Owner: helifu <[email protected]> Gerrit-Reviewer: Adar Dembo <[email protected]> Gerrit-Reviewer: Andrew Wong <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Mike Percy <[email protected]> Gerrit-Reviewer: helifu <[email protected]> Gerrit-Comment-Date: Fri, 09 Aug 2019 04:06:36 +0000 Gerrit-HasComments: No
