I'm looking at o.h.c.i.InfinispanRegionFactory and wondering how best to
configure the 2lc for AS 7.1. After a recent forum discussion and
opening AS7-1544, I need to make some corrections to properly
accommodate multiple JPA persistence units sharing the same underlying
cache definition or having their own.
Currently, with AS 7.0/7.0.1, I think each application should have its
own Infinispan cache definition. In theory, the same cache definition
could be shared if entity class names are unique across all persistence
units (within apps and across different applications). This can be
accommodated currently by adding additional Infinispan configuration
entries to the AS7 standalone.xml (or domain.xml).
One question that I have, is could we add an additional key for
identifying the 2lc cache. The additional key that I have at the time
of creating the container managed entity manager, is the "application
name scoped persistence unit name" (includes the PU name and the
application/containing jar name). Perhaps that could be passed into
InfinispanRegionFactory via a property representing a unique way to
refer to all 2lc entries for a specific applications persistence unit
definition. I'm not sure how desirable it would be to further qualify
the cache entries with this additional information (especially if it
increases the payload transferred during replication).
I think the alternative would be to have each application, configure
their own cache definition (either to share with all applications PU or
create a separate definition per PU). This might be close to what I
already described as a workaround in the
What do you think?
