             Summary: Fix cached Variant with column size greater than 128KB or individual variant larger than 2kb
                 Key: SPARK-49074
                 URL: https://issues.apache.org/jira/browse/SPARK-49074
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 4.0.0
            Reporter: Richard Chen


Currently, the `actualSize` method of the `VARIANT` `columnType` isn't overridden, so we use the default size of 2kb for the `actualSize`. We should define `actualSize` so the cached variant column can correctly be written to the byte buffer
