As per my knowledge, there is common virtual disk.so each Amp is responsible to manage one portion of space (vdisk) leads to shared nothing architecture
So when can we say Shared nothing arcitecture means?.. Each Amp is going to do operations like DDL,DML ,Aggregation function with its own space of vdisk and with its memory
Please correct me,if my expaination is wrong !!.. This query was asked in interview??
