Region.get() is going to return you domain object.
So let's say yoy have domain class with
{
byte[] data
Map<String,Object> other
}
You can say,
Region.get(data).getOther()

Make the value a collection wrapper.

Thanks, wondering if geode can save 2 objects for a single key? So I can
put data and other property separately. Or every key is for 1 object?
Never use the PDX and server side function, is that mean those need to be
deployed to the server? or there is a way to programming register the
function to the server?
Thanks,

+1 on Mike's suggestion for the ReflectionBasedAutoSerializer
To get name and author you could use OQL:

You should probably use the PDX ReflectionBasedAutoSerializer.
Then you can write a server-side function that you call to get just the
fields you want and return them.

Hi,
I have an object comprise of
MyObject{
byte[] data;
String name;
String author;
….
Other properties;
}
Or I can use
MyObject{
Byte[] data;
Other allOther;
}
When I get by key, I only want to get all the properties except the data
itself, because data could be large, is that has to be done with query?
Not sure how the performance of query compare to region.get(key).
Another question is to serialize the data. Do I need to upload the jar
containing MyObject to geode server?
Thanks,
Nan
