Thanks Andy, I will switch to the datanucleus forum for this specific
problem.
More generally, I did hope that adding caching was low-hanging fruit, but
seems its more complex than I imagined. Maybe not the thing to tackle in
the weeks before Christmas.
My app is read intensive, so adding caching

However, the following exception is common to the range of cache
implementations I've tried.
I'm using datanucleus-core.4.1.7.jar
I'll see if Andy will talk to me ..
- java.lang.ClassCastException
- org.datanucleus.identity.SCOID cannot be cast to java.io.Serializable
-
org.datanucleu
No problem.

Sure.. I was just suggesting a couple of paragraphs capturing the contents
of this particular thread, ie how to enable caching.

I'll see what I can do, its a new area for me and alot to read up on. Maybe
even a fast moving area at the moment, with things like Apache Ignite

Thanks for doing this exploration... I've made a note to add something to
the docs, but even better would be a PR from yourself to add it. Perhaps a
new section in "other techniques" chapter of the "beyond the basics" guide
[1,2]?
Cheers

Hazelcast (https://hazelcast.org/) works 'out of the box' as a JSR-170
javax.cache implementation. No config file expected.
I have:
isis.persistor.datanucleus.impl.datanucleus.cache.level2.type=javax.cache
isis.persistor.datanucleus.impl.datanucleus.cache.level2.mode=UNSPECIFIED
isis.persistor.da
Thanks Andy, sorry for my astounding naïveté.
I see now there is a page where JSR-107 implementations are listed:
https://jcp.org/aboutJava/communityprocess/implementations/jsr107/index.html
7.5 Billion people in the world and only one person working on DataNucleus,
why?!

You did not put a Javax.cache provider in your CLASSPATH. As Oscar suggested.
DataNucleus provides "a simple wrapper to javax.c
Hi Oscar,
The way I read the documentation 'javax.cache' as the configuration value
should use a standard caching framework 'out of the box' so to speak.
I can try the other caching options but was wondering if anyone else might
have used that one.
Cheers

Hi Stephen.
Have you tried to add through Maven any of the Java Caches available?
As per [1], seems DN declares a wrapper arround them, so you will need to add
one implementation.
Many are mentioned on the URL you included.
HTH,
Oscar

Hi,
I am interested to try Level 2 caching to see what performance benefits I
can gain.
At the moment I cannot configure it.
In the file persistor_datanucleus.properties I have these settings:
#
# L2 cache
# off except if explicitly marked as cacheable

14 matches
