1. Actually this doc looks misleading and wrong to me. What does it mean "it will not be distributed"? It only means that we will not execute any distributed joins inside of this subquery. In all other means this operation will be correctly distributed.
We will generate query like this : SELECT _key, _val FROM Person WHERE _key IN (subquery) And execute it on all the nodes and if the subquery is correctly colocated with Person everything will work fine. 2. This is not something we are going to change because subquery will be executed for each row in Person. If it will have a distributed join in it, this operation will never return and most probably will kill the cluster by message flooding.
