Hi, I'd like to know more about Apex support for dynamic topology.
>From my readings on Apex, I understand we can add additional parallel tasks for each operator and change data partitioning among them dynamically at run time (so-called data partitioning and unification features). My question is can we change the "logical" DAG at run time? Let's say my logical DAG is a chain of three operators X, Y & Z (i.e., X -> Y -> Z). Now at run time I want to replace operator Y with operator P, such that the new logical DAG would look like X -> P -> Z. Is it something I can do with Apex? Thanks! -hs
