Question - In Teradata, what according to you is the biggest issue, and how it can be avoided simply?
Answer -
The failure of the node is one of the major problems in Teradata. Although the chances are less, it creates several glitches when happens. There is a dedicated feature in Teradata to control this situation and i.e. creating a Clique. The same is actually an assortment of nodes that are shared between the drives which are common. When this approach is considered, the failure of one node doesn’t make much impact.
