Infinispan embedded off-heap cache
by yavuz gokirmak
Hi all,
Is it possible to use infinispan as embedded off-heap cache.
As I understood it is not implemented yet.
If this is the case, we are planning to put effort for off-heap embedded
cache development.
I really need to hear your advices,
best regards

Design change in Infinispan Query
by Sanne Grinovero
Hello all,
currently Infinispan Query is an interceptor registering on the
specific Cache instance which has indexing enabled; one such
interceptor is doing all what it needs to do in the sole scope of the
cache it was registered in.
If you enable indexing - for example - on 3 different caches, there
will be 3 different Hibernate Search engines started in background,
and they are all unaware of each other.
After some design discussions with Ales for CapeDwarf, but also
calling attention on something that bothered me since some time, I'd
evaluate the option to have a single Hibernate Search Engine
registered in the CacheManager, and have it shared across indexed
caches.
Current design limitations:
A- If they are all configured to use the same base directory to
store indexes, and happen to have same-named indexes, they'll share
the index without being aware of each other. This is going to break
unless the user configures some tricky parameters, and even so
performance won't be great: instances will lock each other out, or at
best write in alternate turns.
B- The search engine isn't particularly "heavy", still it would be
nice to share some components and internal services.
C- Configuration details which need some care - like injecting a
JGroups channel for clustering - needs to be done right isolating each
instance (so large parts of configuration would be quite similar but
not totally equal)
D- Incoming messages into a JGroups Receiver need to be routed not
only among indexes, but also among Engine instances. This prevents
Query to reuse code from Hibernate Search.
Problems with a unified Hibernate Search Engine:
1#- Isolation of types / indexes. If the same indexed class is
stored in different (indexed) caches, they'll share the same index. Is
it a problem? I'm tempted to consider this a good thing, but wonder if
it would surprise some users. Would you expect that?
2#- configuration format overhaul: indexing options won't be set on
the cache section but in the global section. I'm looking forward to
use the schema extensions anyway to provide a better configuration
experience than the current <properties />.
3#- Assuming 1# is fine, when a search hit is found I'd need to be
able to figure out from which cache the value should be loaded.
3#A we could have the cache name encoded in the index, as part
of the identifier: {PK,cacheName}
3#B we actually shard the index, keeping a physically separate
index per cache. This would mean searching on the joint index view but
extracting hits from specific indexes to keep track of "which index"..
I think we can do that but it's definitely tricky.
It's likely easier to keep indexed values from different caches in
different indexes. that would mean to reject #1 and mess with the user
defined index name, to add for example the cache name to the user
defined string.
Any comment?
Cheers,
Sanne

singleton @Listeners
by Mircea Markus
This is a problem that pops up constantly:
User: "I add a listener to my distributed/replicated cache but this gets invoked numOwners times - can I make that to be invoked only once cluster wise?"
Developer: "Yes, you can! You have to do that and that..."
What about a "singleton" attribute on the Listener? Would make the reply shorter:
Developer: "Use @Listener(singleton=true)"
Cheers,
Mircea

KeyAffinityService (nice) - 2 recommendations
by cotton-ben
Hi,
First, nice work on org.infinispan.affinity.KeyAffinityService ... May I
make 2 recommendations.
1. Add to the interface an overload =
*K getKeyForAddress(Address address, K otherKey); /*compute
address specific version of otherKey*/*
2. Provide documentation that *explicitly* motivates users to
understand/exercise the differences (and compatibilities) of the
KeyAffinityService API and the Grouping API. Now, that I have some
competency using KeyAffinityService, I am not sure of which use case would
call for my using org.infinispan.distribution.group.Grouper API (unless
maybe to manage a collection of nodes that have custody of key-set(s) pinned
to it by the KeyAffinityService?).
Thanks,
Ben

Using infinispan as quorum-based nosql
by vitalii.tymchyshyn＠ubs.com
Hello.
We are going to use Infinispan in our project as NoSQL solution. It
performs quite well for us, but currently we've faced next problem.
Note: We are using Infinispan 5.1.6 in SYNC_REPL mode in small cluster.
The problem is that when any node fails, any running transactions wait
for Jgroups to decide if it've really failed or not and rollback because
of SuspectException after that. While we can live with a delay, we'd
really like to skip rolling back. As for me, I actually don't see a
reason for rollback because transactions started after leave will
succeed. So, as for me, previously running transactions could do the
same.
The question for is if node that left will synchronize it's state after
merge (even if merge was done without infinispan restart). As for me, it
should or it won't work correctly at all.
So, I've found RpcManager's ResponseMode.SYNCHRONOUS_IGNORE_LEAVERS and
think on switching to it for RpcManager calls that don't specify
ResponseMode explicitly. As for me, it should do the trick. Also, I am
going to enforce Quorum number of reponses, but that's another story.
So, how do you think, would it work?
P.S. Another Q for me, how does it work now, when SuspectException is
thrown from CommitCommand broadcasting. Af far as I can see, commit is
still done on some remote nodes (that are still in the cluster), but
rolled back on local node because of this exception. Am I correct? This
can cause inconsistencies, but we must leave with something in
peer-to-peer world :) The only other option is to switch from write-all,
read-local to write-quorum, read-quorum scenario that is too complex
move for Infinispan as for me.

Re: [infinispan-dev] Removing Infinispan dependency on the Hibernate-Infinispan module in 4.x
by Galder Zamarreño
Scott, what do you suggest doing instead then? Without the commands, evictAll invalidation won't work.
Are you suggesting that I revert back to using the cache as a notification bus so that regions are invalidated?
