> Vector validator to diagnose offset vector issues
> -------------------------------------------------
>
> Key: DRILL-5504
> URL: https://issues.apache.org/jira/browse/DRILL-5504
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
> Fix For: 1.11.0
>
>
> 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.
