Igor Suhorukov updated ARROW-17431:
-----------------------------------
Description:
Typical real life Arrow datasets contain Map type vectors of string key->string
value. Looks logically implement default JDBC parameter binders for such vector
type or implement some kind on binder code extensibility of core framework via
MetaINF/ServiceLocator
Current implementation just [throws
UnsupportedOperationException|https://github.com/apache/arrow/blob/master/java/adapter/jdbc/src/main/java/org/apache/arrow/adapter/jdbc/binder/ColumnBinderArrowTypeVisitor.java#L100]]
{code:java}
@Override
public ColumnBinder visit(ArrowType.Map type) {
throw new UnsupportedOperationException("No column binder
implemented for type " + type);
} {code}
