Storing null values in avro files

Question

I have some json data that looks like this:

  {
    \"id\": 1998983092,
    \"name\": \"Test Name 1\",
    \"type\": \"search string\",
    \"creationDate\": \"2         


        

Answer 1

I have this issue too and now resolved it.

I found @Nullable annotation in Apache Avro to declare the field is nullable.

So, in this example, we should

import org.apache.avro.reflect.Nullable;

public class MyAvroRecord {
    long id;
    String name;
    String type;
    Date timestamp;
    Date lastModifcationDate;
    String lastModifiedUsername;
    @Nullable
    Boolean lockedQuery;
}
