Broadcast join mechanism
Hi, I am wondering that what the broadcast join mechanism is. For some reason, I cannot setup all nodes in my cluster in ONE sub-network. 1) Is it mean that the broadcast join in my cluster are actually a "multicast join"? 2) In a broadcast join, would vertica broadcast the data to each sub-network? or would vertica unicast the data to each node? 3) In the documentation, I found that only UDP and TCP were mentioned. Which protocol would vertica use in a broadcast join?
