I was playing around
```
import org.apache.beam.sdk.coders.AvroCoder;
import org.apache.beam.sdk.coders.DefaultCoder;
import org.apache.beam.sdk.coders.RowCoder;
import org.apache.beam.sdk.coders.SerializableCoder;
import org.apache.beam.sdk.schemas.JavaBeanSchema;
import org.apache.beam.sdk.schemas.annotations.DefaultSchema;
@DefaultSchema(JavaBeanSchema.class)
@DefaultCoder(AvroCoder.class)
public class UserData {
private String name;
private String lastname;
public UserData(String name, String lastname) {
this.name = name;
this.lastname = lastname;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
}
```
and now i triggered this:
```
