Hi all,


We bumped the limit as of 1.4.0 but the new docs haven't been re-published, you can still see them here:https://github.com/apache/kudu/commit/0e41d4cce5ca96cb08612475f76539f6c8bc58f1


Hope this helps,


J-D

there are multiple issues that interact but one issue is that if you have many tablets you will use many threads. Adar has been focusing on improving density lately and trying to quantify the scaling limits.

what will happen if the data more than 4T? the disk is large than before. 6T a disk is is common, there any test data or doc?
