Infinispan URL format
by Tristan Tarrant
In the past there has been talk of representing a connection to
Infinispan using a URL, in particular for HotRod.
The Hibernate OGM team is now working on adding NoSQL datasources to
WildFly, and they've asked for they should represent connections to
various of these.
For Hot Rod:
infinispan:hotrod://[host1][:port1][,[host2][:port2]]...[/cachemanager]
The [cachemanager] part is for multi-tenant servers (Hot Rod doesn't
currently support this, so this is forward-looking).
Obviously we will support all of the HotRod properties for specifying
things like security, etc.
For Embedded:
infinispan:embedded:file://path/to/config.xml (for specifying an
external config file)
infinispan:embedded:jndi://path/to/jndi (for referencing a cachemanager
in JNDI)
infinispan:embedded: (configuration specified as properties)
For the latter, we also need to be able to represent an infinispan
configuration using properties with a simple mapping to XML
elements/attributes, e.g.
cache-manager.local-cache.mycache.eviction.size=1000
Comments are welcome

Singleton Cache Stores with Shared Cache Stores
by William Burns
Recently there was a start of a discussion regarding singleton cache stores
and how they behave. Interestingly according to our documentation [1] and
verification code [2] a singleton store cannot be used with a shared cache
store. This makes no sense to me as this means you would have a single
point of failure for your data. And also as Dan pointed out [3] there is
no Singleton cache loader to make sure all the loads are from the
coordinator either, which means you could have a read that returns null
despite it being in the store/loader.
And even looking at [4] it talks about singleton being used so not every
node writes to the underlying store, which implies it being shared.
I think we have enough proof to update this so a singleton store requires a
shared store, but I wanted to make sure we weren't missing something here.
Thanks,
- Will
