Class EnterpriseDataSerializableSerializer

java.lang.Object

com.hazelcast.internal.serialization.impl.EnterpriseDataSerializableSerializer

All Implemented Interfaces:

com.hazelcast.nio.serialization.Serializer, com.hazelcast.nio.serialization.StreamSerializer<com.hazelcast.nio.serialization.DataSerializable>, com.hazelcast.nio.serialization.TypedStreamDeserializer<com.hazelcast.nio.serialization.DataSerializable>

public final class EnterpriseDataSerializableSerializer
extends Object
implements com.hazelcast.nio.serialization.StreamSerializer<com.hazelcast.nio.serialization.DataSerializable>, com.hazelcast.nio.serialization.TypedStreamDeserializer<com.hazelcast.nio.serialization.DataSerializable>

The StreamSerializer that handles:

1. DataSerializable
2. IdentifiedDataSerializable

This is the enterprise version of the DataSerializableSerializer that handles the versioning. Each object annotated by the @Versioned annotation will get the cluster major.minor version included in the byte stream if the cluster version is not set to UNKNOWN. It is only used if rolling-upgrades are enabled (for backward compatibility).

We don't send the patch version since there it is impossible to put patch version releases in a time ordered sequence. 3.8.5 might have been released after 3.9.2. In order to know that we would have to hard-code the release order into the code. What we can order are the minor releases -> it's obvious that 3.8 was released before 3.9.

What is more, there should not be any byte format differences between patch releases. Between two patch releases everything should work out-of-the-box due to our binary compatibility policy and we don't want to change that. Enabling binary versioning among patch releases would cause a lot of overhead and would make our coding and testing process massively more complex.
