Hi all.
I create one cluster with SIZE 2K .
This cluster include 2 table(master/detail) with about 5 million record.
I want reduce SIZE parameter to 1K for this cluster.(for reduce space allocation by this cluster)
command (ALTER CLUSTER MY_CLUSTER SIZE 1K
reduce SIZE for upcoming records no for existing records.

Is it possible to rebuild cluster with SIZE 1K?

-- sorry for my english.
Best Regards.
