I gone through the document. Gave good insight information on this. Have few below questions

1) Suppose if we receive incremental data with some modifications to existing record and in this case whether existing clustered ZCubes will be re-organized again? In this case many existing organized clustered Zcubes will be processed again to maintain the data locality?

2) Once the table is created with Liquid clustering then how we check which columns are used for LC?

3) So Z-ordering syntax cannot be used in Create or Alter table query (how we do in case of LC) and needs to execute only with Optimize command?
