> DRILL-5470 describes a case in which an offset vector appears to have become corrupted, yielding a bogus field-length value that is orders of magnitude larger than the vector that contains the data.
> Debugging such cases is slow and tedious. To help, we propose to create a "vector validator" that spins through vectors looking for problems.
> Then, to allow the validator to be used in the field, extend the "iterator validator batch iterator" to optionally allow vector validation on each batch.
