Subject [jira] Commented: (LUCENE-1473) Implement standard Serialization across Lucene versions
Date Fri, 05 Dec 2008 23:17:44 GMT

Doug Cutting commented on LUCENE-1473:
--------------------------------------

> I guarantee 2.9 and above classes will be backward compatible with the previous classes.

It sounds like you are personally guaranteeing that all serializeable classes will be forever
compatible.  That's not what we'd need.  We'd need a proposed policy for the project to consider
in terms of major and minor releases, specifying forward and/or backward compatibility guarantees.
 For example, we might say, "within a major release cycle, serialized queries from older releases
will work with newer releases, however serialized queries from newer releases will not generally
work with older releases, since we might add new kinds of queries in the course of a major
release cycle".  Similarly detailed statements would need to be made for each Externalizeable,
no?

> To maintain serialization compatibility between Lucene versions, serialVersionUID needs
to be added to classes that implement java.io.Serializable.  java.io.Externalizable may be
implemented in classes for faster performance.
