What does "handle" mean in this case? You are inserting 20TB of new data
each day, so that your total dataset grows by that amount? How much data do
you retain? How many nodes is your cluster? (I would guess many hundred?)

If you are seeing Kudu as an "improved HBase" that isn't really accurate.
Of course there are some things we can do better than HBase, but there are
some things HBase can do better than Kudu.

As for Kudu data sizes, I am aware of some organizations storing several
hundred TB in a Kudu cluster, but I have not yet heard of a use case with
1PB+. If you are looking to run at that scale you may hit some issues, but
we are standing ready to help you overcome them. I don't see any
fundamental problems that would prevent it, and I have run some basic smoke
tests of Kudu on ~800 nodes before.

Hope some other users can chime in.
