WebSphere eXtreme Scale V8.6 IBM Extreme Scale

Question

I am trying to figure out how big my objects are when serialized in ObjectGrid (IBM Extreme Scale). I want to add more data to the object but want to see how much increase in space it will take. Is there a way I can determine this? For instance, can I call a method on any of the object grid classes to get the bytes?

Thanks

In order to see the size of the serialized value of an inserted entry into the grid you would do code like the following:

ObjectMap map = session.getMap("map");
map.setValueOutputFormat(OutputFormat.RAW);
SerializedValue sv = (SerializedValue) map.get(key);
int size = sv.getInputStream().size();
System.out.println("The serialized size of the value for key " + key + " is " + size);
