That seems exactly what the inner of `Table` does. Do we have some util or a
`copy` method for that. Or I just wrap by myself .. It seems quite a common
usage and I don't want to hook outside of arrow-java.
```java
while (reader.loadNextBatch()) {
final VectorSchemaRoot source = reader.getVectorSchemaRoot();
final VectorUnloader unloader = new VectorUnloader(source);
final VectorSchemaRoot copy =
VectorSchemaRoot.create(source.getSchema(), allocator);
final VectorLoader loader = new VectorLoader(copy);
loader.load(unloader.getRecordBatch());
batches.add(copy);
}
```
