As per my knowledge : actually clusters will be using to not to have down time in the source system. mpp means massivly parlell processing (i.e parlelly processing from the source to target massively by placing multiple processors) but coming to cluster point,
first of all when ever we are fetching data from one 'A'system to 'B' system,'A' system should be down then only we can fetch data from 'A' to 'B'.
so now here by using cluster we do not want to down the 'A' system |
