----------------------------------
Summary: 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.
