Infinispan Serialization

jmfaerman Aug 7, 2012 3:02 PM

Hello,

I have tried getting an instance from the cache that was put with a different serialVersionUID and class changes, but it works fine... serializing to a file it does not.

Is the defaul serialization in infinispan any different from standard java serialization?

Regards,

Julio

Infinispan uses a custom (pluggable) serializer for its internals: https://docs.jboss.org/author/display/ISPN/Plugging+Infinispan+With+User+Defined+Externalizers
Can you elaborate a bit on what/how gets serialized to a file, and how do you read that?

I have created a simple POJO with a few properties and put it to infinispan and serialized it to disk.

Then i changed the class, including the serialVersionID, and tried do retrieve the object.

I noticed that the infinispan returns the object silently and the java serialization fails, and that got me wondering, but as your reference explains, it must be a feature from JBoss Marshalling.

Thanks for the clarification.

Every object stored in infinicache must have Externalizer serializer? I want to use cache with overflow to disk.

@Radim, no. The requirements and benefits of each approach are explained in https://docs.jboss.org/author/x/PwY5
