Questions about this documentation (by Ben Gelernter, tech writer):
The partitioning policies in the spec at http://wiki.eclipse.org/EclipseLink/DesignDocs/328937 don't seem to match the partitioning policies in the Javadoc (from the zip download) at zip/eclipselink-2.2.0.v20110114-r8831/eclipselink/eclipselink-javadocs/org/eclipse/persistence/descriptors/partitioning/package-summary.html.
This draft (1/26/11) is based on the Javadoc. Is that correct? That is, this doc should follow the Javadoc, not the spec on this matter, correct?
The differences are:
- CustomPartitioningPolicy and PinnedPartitioningPolicy are in the Javadoc, but not in the spec.
- There are alternative names given for the policies in the spec, under the Functionality section. Shall I assume the names in the Javadoc are correct and the alternative names in the spec should be ignored? Or are they referring to some other kind of entity?
The following table sums up the differences:
|Spec under "Functionality"||Spec under "API"||Javadoc|
|not listed||not listed||CustomPartitioningPolicy|
|not listed||FieldPartitioningPolicy||same as API in spec|
|HashPartitionPolicy||HashPartitioningPolicy||same as API in spec|
|not listed||PartitioningPolicy||same as API in spec|
|RoundRobinPolicy||RoundRobinPartitioningPolicy||same as API in spec|
|RangePartitionPolicy||RangePartitioningPolicy||same as API in spec|
|ReplicationPolicy||ReplicationPartitioningPolicy||same as API in spec|
|UnionPartitionPolicy||UnionPartitioningPolicy||same as API in spec|
|ValuePartitionPolicy||ValuePartitioningPolicy||same as API in spec|
As of build v20100819-r8063, I still don't see any of these APIs in the online Javadoc at http://www.eclipse.org/eclipselink/api/2.2/index.html. Is there a reason for that? When will it appear?
The spec gives an example of an orm.xml file but only has a bullet item for persistence.xml. Should there be an example for persistence.xml, too?
Under "Requirements," the spec lists failover, UCP and RAC as "Phase 2." So, should the "Data Affinity, Oracle RAC, and JDBC UCP Support" section in the current draft be removed?
And nothing needs to be said about failover for this release, correct?
I'm not sure what specifically to say about the listed connection pool properties in this context. Can anyone offer some choice phrases for an introduction?
