Hi Jonu
as of now (rev. 82) the SAP HANA query optimizers don't use stored object statistics in most cases (SDA tables can be an execption to this).
Since most of the relevant data/object statistics is available on the fly, we don't need to store them or to seperately collect them in CBO stats batch runs.
In marketing speech: yet another simplification for systems operations on SAP HANA
