This data store holds many types of data structures such as Queues, Maps, Multimaps, Locks, Semaphores etc. So the last thing to reveal is domain model serialization. * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. It allows classes to implement their own serialization logic directly instead of using a separate Serializer implementation. After registering these classes, serialization performance can be greatly improved, especially for small numbers of nested objects. * Hopefully I discovered that guys from Esoteric Software think about remote communication and they did very logic step. This class orchestrates the serialization process and maps classes to Serializer instances which handle the details of converting an object's graph to a byte representation. Spring defines the following implementation of cacheManger. However without registry, kyro is a little slower(2.1s->2.5s, jdk is 14.1s)) and add related testcases.
