Hazelcast Predicate SQL into map - hazelcast

Question

I'm trying to build a method that deletes entries with attributes that are not null, but I keep failing in predicates and I don't know how to implement properly the predicate because hazelcast doesn't take "NOT NULL" or "IS NULL" as a where clause Any idea how can I find into the map the values I need to search to delete them?
the method
public int removeEntry(String CacheName, String claveReq, int id_interno_pe, String cod_nrbe_en, int num_sec_ac) {
int counter = 0;
IMap<String, ResponseSerializablePlus> map = clientInstance.getMap(CacheName);
// Predicate claveReqQuery = Predicates.equal("claveReq", claveReq);
// Predicate idInternoQuery = Predicates.equal("id_interno_pe", id_interno_pe);
// Predicate codNrbeQuery = Predicates.equal("cod_nrbe_en", cod_nrbe_en);
// Predicate numSecQuery = Predicates.equal("num_sec_ac", num_sec_ac);
// Predicate query = Predicates.and(idInternoQuery,codNrbeQuery,numSecQuery);
Predicate query = Predicates.sql("id_interno_pe IS NOT NULL");
if (!map.isEmpty()) {
for (ResponseSerializablePlus entry : map.values(query)) {
System.out.println("Entry "+entry.toString()+" Found");
map.delete(entry);
counter++;
}
System.out.println("Map Size ->"+map.size());
System.out.println("Deleted entries -> "+counter);
return counter;
}else {
System.out.println("No matches");
return 0;
}
}
the main class ResponseSerializablePlus
public class ResponseSerializablePlus implements IdentifiedDataSerializable{
private int id_interno_pe;
private String cod_nrbe_en;
private int num_sec_ac;
private int statusCode;
private HashMap<String,List<String>> headers;
private byte[] content;
public ResponseSerializablePlus(int id_interno_pe, String cod_nrbe_en, int num_sec_ac, int statusCode,
HashMap<String, List<String>> headers, byte[] content) {
this.id_interno_pe = id_interno_pe;
this.cod_nrbe_en = cod_nrbe_en;
this.num_sec_ac = num_sec_ac;
this.statusCode = statusCode;
this.headers = headers;
this.content = content;
}
public ResponseSerializablePlus() {
}
public void writeData(ObjectDataOutput out) throws IOException {
out.writeInt(id_interno_pe);
out.writeString(cod_nrbe_en);
out.writeInt(num_sec_ac);
out.writeInt(statusCode);
out.writeObject(headers);
out.writeByteArray(content);
}
public void readData(ObjectDataInput in) throws IOException {
this.id_interno_pe = in.readInt();
this.cod_nrbe_en = in.readString();
this.num_sec_ac = in.readInt();
this.statusCode = in.readInt();
this.headers = in.readObject();
this.content = in.readByteArray();
}
public int getFactoryId() {
return ResponseSerializablePlusFactory.FACTORY_ID;
}
public int getClassId() {
return ResponseSerializablePlusFactory.RESPONSE_SERIALIZABLE_PLUS_CLASS;
}
#Override
public String toString() {
return "ResponseSerializablePlus [id_interno_pe=" + id_interno_pe + ", cod_nrbe_en=" + cod_nrbe_en
+ ", num_sec_ac=" + num_sec_ac + ", statusCode=" + statusCode + ", headers=" + headers + ", content="
+ Arrays.toString(content) + "]";
}
}

It's indeed not supported, and it's document, along with the alternative option. Have a look here: https://github.com/hazelcast/hazelcast/blob/3cb8ce1fc3bb848aced6c87a30bf7b31aec16cf7/hazelcast/src/main/java/com/hazelcast/query/Predicates.java#L492-L497
