Java – how to get entity size in gae / J?

The gae document mentions that the maximum entity size is 1MB Because I store a lot of data in entities, I want to know when I approach this limit

I know the gae / Python method model_ to_ protobuf(..), But I can't find anything Java

I also know that gae internally uses protobuf to serialize entities, so I can do the same But I want to avoid duplicate code because gae has done it behind the scenes

Is there a programming way to get the entity size in Java, preferably before actually storing the entity?

Solution

It seems that this method should fit your bill:

public static EntityProto convertToPb(Entity entity)

And match the content you find on the python side
