Donald Woods updated OPENJPA-1334:
----------------------------------
Fix Version/s: (was: 2.0.0)
2.0.0-M4
Comment from Pinaki in an email about r828880 -
1. introduces a JPAProperties class. It is in preliminary stage but its
purpose is to corral all JPA property key/value manipulation. If you are
playing with JPA properties and needs more support, please consider adding them
to this class rather than spreading them.
2. Or know of some related processing happening elsewhere please consider
relocation. For example, I found the following logic tucked in
FetchPlanHintHandler...which may now live in JPAProperties.
// to accomodate alias name input in relationship with enum values
// e.g. "optimistic-force-increment" ==
// LockModeType.OPTIMISTIC_FORCE_INCREMENT
String strValue = ((String) value).toUpperCase().replace('-', '_');
3. Changed use of implementation to interfaces in HintHandler. Please note
that implementations are preferred not only for architectural aesthetics or
programming discipline, but also helps any other downstream plug-ins.
4. Used FetchPlan to carry these cache mode properties from facade to
kernel. This decision aligns better with other configuration properties such as
lock modes etc, and also tagging them on FetchPlan helps to reuse tested
pathways. This change deprecated supporting methods/constructs appearing in
StoreContext.

> OpenJPA models L2 cache as one or more named partitions. And is able to
> assign a managed instance to a named partition. However, this distribution of
> managed instances to specific named partition is based on the instance's type
> and not an the instance itself. The type based as distribution allows the
> named cache partition be specified at metadata level.
> This proposed feature is to introduce a distribution policy that extends the
> support for instance based distribution policy.
