> Assume two concurrent update queries- Query A and Query B , that have overlapping updates.
> If Query A commits the data and delete files first, then Query B will fail with validation failure due to conflicting writes. 
> In this case, Query B should invalidate the commit files that are already generated and re-execute the full query on the latest snapshot.
