Bulk load mechanism in a cluster

hoseiney

I read about MPP (massively parallel processing) mechanism in Vertica and Understand in a cluster, queries execute in each node separately and parallel( one initiator node and other nodes are executors)
So what about copy command ?
Does it have same mechanism?

Hi. Welcome to the board. I think you'll like the following information in our documentation:

I just checked with SKamat, another poster on this board, and the COPY command supports MPP through options, such as APPORTIONED LOAD

and COPY ON ANY NODE
