   > If a TaskContext represents a query/task
   
   I think it might be more precise to describe `TaskContext` as the state for query execution, with `SessionState` used for query planning.
   
   > the only way right now to identify task in TableProvider
   
   Correct, at the point in planning where `TableProvider::scan` is called, the task conceptually doesn't exist yet
   
   > create new SessionContext for each query
   
   FWIW this is what IOx does
