             Summary: Support Apache Arrow View types in ArrowColumnVector
                 Key: SPARK-57929
                 URL: https://issues.apache.org/jira/browse/SPARK-57929
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core, SQL
    Affects Versions: 4.1.2
            Reporter: Robert Kruszewski


Apache Arrow have added View types in 1.4 of the spec. The arrow-java version in use in spark already has support for them. Modern data systems might choose to produce those arrow types instead of usual List/Utf8/Binary types since they support random reads and writes without having to reallocate whole vector. Spark should support reading those vectors in its columnar execution
