Cannot create table clusters on ADB shared infrastructure

Summary:

Cannot create table clusters on ADB shared infrastructure

Content (required):

Is it intended that u cannot assign tables to clusters on adb? Instead Oracle is creating an index on the specified columns in the cluster clause.

I cannot find any documentation about that feature being not supported on shared infrastructure.

What would be a good alternative solution to store ecommerce data from multiple shops in the same tables without running into performance issues? For example

Customer (shop_id, cust_id, ...)

Product (shop_id, prod_id, ...)

Order (shop_id, order_id, cust_id, ...)

Line Item (shop_id, line_id, order_id, product_id, ...)
