vm select node
Describe the question in detail
is there a way way to deploy the vm select node, which can let the vm select node get data from another select node?
i want to deploy my vm cluster like this:
a vm select node and a vm storage node deploy in the same host, then there is another select node on the higher level, the higher level select node accept request and send request to vm select node which is on the same host with storage, the lower level select node can agg(like sum, count ) the data from the storage node which on the same host, this can avoid large flow by net and the high level select node can get data from lower level select node ,calculate the right answer because sum(A+B) = sum(A) + sum(B)
the select node can communicate with the storage node which on the same node by mem or directly read the file to optimize the latency between select and storage node.and Resource is isolatio beetween two process.just like pushdown the operator.
