Oracle Coherence 3.5

Implementing object serialization

One of the most important choices you need to make for your domain objects (from the Coherence perspective) is how they will be serialized. Coherence works just fine with objects that simply implement java.io.Serializable interface, so that is typically the easiest way to try things out. However, that is also the slowest way to serialize your objects, as it heavily depends on reflection. It also introduces a lot of overhead into the object's serialized binary form, as it embeds into it things such as full class name, field names, and field types.

Serialization performance will impact most operations against a distributed cache, while the size of the serialized binary form will not only have an impact on network ...
