-------------------------------------
Summary: [Java] JDBC adapter does not preserve SQL-nullability
Key: ARROW-12679
URL: https://issues.apache.org/jira/browse/ARROW-12679
Project: Apache Arrow
Issue Type: Bug
Reporter: Joris Peeters
Assignee: Joris Peeters
When using the JDBC adapter, the schema of the VectorSchemaRoot's in the
ArrowVectorIterator have all the columns as nullable, irregardless of whether
they are nullable in SQL.
This should be fixed, so that the schema has only those columns as nullable
that are also nullable in SQL.
