Re: [infinispan-dev] https://issues.jboss.org/browse/ISPN-977
First thing I thought when reading your email was "OMG do we support
on-the-fly hash implementation changes? crazy!"
That's obviously not the case, but if you name it as
@ConsistenHashChangeListene that's what I would think.
Wouldn't it be better to change the exact timing of the viewchange
event? I don't see why Infinispan users might be more interested in
knowing about the topology details according to the transport than
what they are about the actual Infinispan hashing topology - I would
expect that when I receive which notification the new view is already
installed and ready to go; actually I thought that was the case since
ever.
What would be the use cases to get the notification *before* the new
hash is installed?

Hi,
The basic problem behind this is that I need to be notified when a new
consistent hash is installed.
ATM there isn't any support (of which I know) for a
"@ConsistenHashChangeListener".
I'm thinking to add such notifications either:
a) internally: Observer pattern on DistributionManager or even on
DistributionManagerImpl
b) more generically, as a fully flagged listener.
I favor a) and then if more people ask for it we will expose it as a fully
flagged listener.
Suggestions?
Cheers,
Mircea
