> When dealing with records coming from Java classes, Avatica relies on the
> order of fields coming from {{java.lang.Class#getFields}} instead of using
> the order defined in the underlying SQL data type:
> # [org.apache.calcite.avatica.MetaImpl#createGetter(int
> ordinal)|https://github.com/apache/calcite-avatica/blob/ba20936bb1387793f34ae489760ec0cdbe205e4e/core/src/main/java/org/apache/calcite/avatica/MetaImpl.java#L145]

> [org.apache.calcite.avatica.util.RecordIteratorCursor#RecordIteratorCursor(Iterator<E>
> iterator, Class<E>
> clazz)|https://github.com/apache/calcite-avatica/blob/ba20936bb1387793f34ae489760ec0cdbe205e4e/core/src/main/java/org/apache/calcite/avatica/util/RecordIteratorCursor.java#L42]
> This behaviour prevents the change of fields orders, and it's particularly
> problematic because {{#getFields}} is JVM-specific.
