Hi Guys,

I have an application that use a remote cache with key as String and value is a HashSet and when my application execute I check that its not performing as well. I know that the better way is always use a Complex Object to be store in Cache, but I want know if anybody have used Collection Type like List, Map or Set as a value in cache and what a implementation used.

To complements, I'm using a HashSetMarshaller.java to write a value cache.

import org.infinispan.protostream.MessageMarshaller;


import java.io.*;
import java.util.HashSet;


public class HashSetMarshaller implements MessageMarshaller<HashSet> {


  @Override
  public String getTypeName() {
  return "java.util.HashSet";
  }


  @Override
  public Class<? extends HashSet> getJavaClass() {
  return HashSet.class;
  }


  @Override
  public HashSet readFrom(ProtoStreamReader protoStreamReader) throws IOException {
  byte[] readBytes = protoStreamReader.readBytes("bytess");
  ByteArrayInputStream byteIn = new ByteArrayInputStream(readBytes);
  ObjectInputStream in = new ObjectInputStream(byteIn);
  try {
  Object readObject = in.readObject();
  return (HashSet) readObject;
  } catch (ClassNotFoundException err) {
  throw new IllegalArgumentException("Erro durante leitura de objeto.", err);
  }
  }


  @Override
  public void writeTo(ProtoStreamWriter protoStreamWriter, HashSet hashSet) throws IOException {
  ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
  ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
  objectOutputStream.writeObject(hashSet);
  protoStreamWriter.writeBytes("bytess", byteArrayOutputStream.toByteArray());
  }
}
