parallel (even if there is one file it can read from row groups in
parallel). There is no guarantee these reads will finish
sequentially.
2) Hmm, this one will work for now, because the executor==nullptr
behavior is to borrow
Hey all,
While investigating the in-order behavior of the SourceNode, we found some
interesting observations:
1) The ExecContext should use nullptr for its executor to guarantee any
sequential behavior (as discussed previously). We found cases where our
File BatchReader was reading out of order w
