> We serialize POStore too early in the JobControlCompiler. At that time, storeFunc have
unconstraint link to other operator; in the worst case, it will chain the whole physical plan.
Also, in multi-store case, POStore has link to its data source, which is not needed and will
increase the footprint of serialized POStore.
