Back from Snowcamp 2018
This week, I’m recovering from the Snowcamp 2018 conference in Grenoble. I had an amazing time there, where I could hang-out with people from the french community, discussing tech, coding, non-blocking APIs, lifestyle and diversity!
My talk was on Thursday at 15:00. It was very exciting for me because I was live-coding in front of so many people for the first time! I got very valuable feedback from attendees and speakers to improve my content, live-coding skills and encouragements to submit this talk to other user groups and conferences this year.
This presentation focuses on the work we have been doing to provide a new API available in Infinispan 9.2 (final release coming very very soon!!!): Clustered Locks. These locks are distributed and non blocking, allowing us to synchronise protected code between different Infinispan nodes across a cluster.
It’s a 45 minutes talk, so I’m not presenting the API just from the user point of view; instead I go deep into the actual Clustered Locks internals. We have built this first implementation on top of existing Infinispan’s APIs, which proves that they can be used to do much more than just speeding your applications and caching!
The first user of these locks is the Vert.x-Infinispan Cluster Manager. Before going into the implementation details, I show how to create a cluster of Vert.x applications using Infinispan and a simple example of when and how to use a Vert.x Lock. Underneath Vert.x Locks, the next release of the cluster manager will be using the Clustered Locks API. I’m preparing a longer article on this matter, so stay tuned! Meanwhile, enjoy the presentation slides!

Infinispan coming to Snowcamp 2018
This week, the 25th of January, I will be presenting a talk about Clustered Locks at the Snowcamp 2018 conference in Grenoble (France). During the live-coding talk, I will share the design and code I’ve been working on to create this first version of the clustered locks. These locks will be used by the Vert.x Cluster Manager, but they can be useful to any Infinispan user since version 9.2 (final release coming very soon!!). If you are planning to use this API, we would love to hear from you to give us some feedback and keep us posted on your use case!
If you are attending the conference, fell free to reach me to discuss about Infinispan+Vert.x, locks, Multimap, cute names or any other topic that you care about!
See you!

Infinispan 9.2.0.Beta1 and 9.1.3.Final have been released
Dear Infinispan Community,
Two new releases are ready for you today, our newest and greatest 9.2.0.Beta1 and an updated Final of our stable branch, 9.1.3. Both can be found as usual on our download page.
The highlights of 9.2.0.Beta1 are:
-
New API for querying using Ickle via the REST server, taking advantage of the JSON/Protobuf interoperability [ISPN-8113].
-
Clustered Locks, first experimental release. A ClusteredLock is a data structure used for concurrent programming between Infinispan instances in cluster mode.
-
Clustered Counters have received serveral improvements. It’s now possible to manage your counters via JMX [ISPN-7926] and other management methods are on the way. The strong counter has a new method: compare-and-swap [ISPN-8489]. If you used compare-and-set, the compare-and-swap may improve your code performance. And last but not least, a new sync() method was added to the strong and weak counters, useful if you don’t want to handle the CompletableFuture! https://issues.jboss.org/browse/ISPN-8379
-
Clustered Cache Configuration: Both EmbeddedCacheManager and RemoteCacheManager now have an API for creating/removing caches across the cluster [ISPN-7776]. Caches created with this API will also be created on any new members that will join the cluster. Additionally, the configuration for caches created in this way can be made persistent so that they are automatically recreated when a cluster restarts.
-
Server deployment of Lucene analyzers for remote query [ISPN-7714]. https://issues.jboss.org/browse/ISPN-7865
9.1.3.Final and 9.2.0.Beta1 both add several Off-heap improvements and fixes.
Full details of the new features and enhancements included in these two releases can be found here and here.
We have even more exciting stuff coming up for Infinispan 9.2. Thank you for following us and stay tuned!
The Infinispan Team
