Re: persist only on delete

Hi Val,

just curious about why onAfterRemove(Cache.Entry(K,V) entry)

entry.getValue() sometimes return null.  but I never put a null value into the cache.
I have to check it to avoid NullPointerException.

Thanks

Shawn

Hi Val,

Thanks very much. CacheInterceptor is the best way.

Hi Shawn,

Your approach sounds a bit dangerous. Store is called within an entry lock,
which means that if you do a distributed get there, you will likely get
thread starvation. This should not happen on stable topology, but if another
node fails or joins, you can get stuck.

I think you should use interceptor instead:
