Hi guys
For a little background, see the discussion at
https://issues.jboss.org/browse/ISPN-1586
How do you feel about discarding the contents of the cache store on all cache
(virtual) nodes except the first to start?
I think that's a that might work for replicated caches, but not for
distributed. Imagine this scenario: a DIST cluster is turned down for
maintenance, now when it is started again the preload data, except the fist
node to start, is lost.
Configuring purgeOnStartup=true is not ok in data grid scenarios, because
you'd lose all the data on restart. But loading entries from the cache store
of a node that started later is almost guaranteed to lead to stale data. In
some use cases that stale data might be acceptable, but in most cases it
probably isn't. So perhaps it makes sense to make this configurable?
Cheers
