> LogicalPlan has an isStreaming bit, but it's incompletely implemented. Some 
> streaming sources don't set the bit, and the bit can sometimes be lost in 
> rewriting. Setting the bit for all plans that are logically streaming will 
> help us simplify the logic around checking query plan validity.
