Hi Arrow Community, With the release of Acero, we were wondering if Acero can be used in a distributed environment as for now it looks like Acero is only intended for a local context. For example, if we have a query plan with a hash join node at the root and multiple filter project nodes on each sides of the tree, each side having a data source, how can we distribute the query plan between 3 nodes: 2 nodes containing data sources and executing the filter and project parts of the query plan in parallel while 1 node serving as the compute node, performing only the join operation on the results from the other 2 nodes. As per my understanding, we need some form of RPC mechanism between the ExecNodes of an ExecPlan and would probably be integrated within the Flight framework. Is that the right way to think about it ? Do you think that is something the Arrow community would be interested in if not already planning for it ? Thanks.
