Infinispan 12.0.0.Dev01

Dear Infinispan community,

The first of our development releases of Infinispan 12 is here and it features our upgrade to Hibernate Search 6 which finally allows us to upgrade to Lucene 8.x. We’ve had to change a few things in our query implementation to accommodate the latest and greatest and to make the feature simpler to use. As expected, being a development release, there are some rough edges and we’d really love YOUR help in making sure that we get everything right for the final release later this year.

You can look at the release notes to see what has changed.

We’re hard at work on new features, improvements and fixes, so watch this space for more announcements!

Infinispan 11.0.0.Final

Dear Infinispan community,

We’re proud to announce the release of Infinispan 11. In the tradition of assigning beer codenames to our releases, we decided that "Corona Extra" would be a significant representation of the period during which most of the development has happened. We hope that you, your families and friends have not been impacted by the pandemic.

But didn’t you release 10.x not long ago ?

Indeed, but version numbers are just that: numbers. We are still continuing our near-quarterly releases, but, from now on, these will be identified by major version numbers.

So, what’s new in Infinispan 11 ?

As usual we added new features, improved existing ones and prepared the groundwork for upcoming features.

Conflict detection and resolution for Asynchronous Cross-Site Replication

Cross-site replication is one of our most used features, as it enables a number of very useful use-cases such as geographical load distribution, zero-downtime disaster recovery and follow-the-sun data centers.

In this release we completely overhauled the way we implement asynchronous cross-site replication by introducing conflict resolution, based on vector clocks, as well as multiple site masters to increase throughput and reliability. This means that you can have multiple active sites safely replicating data between each other.

Server security overhaul

Infinispan Server’s security, while very powerful, was also tricky to set up because of the configuration complexity. Since we wanted to make the server secure by default, we put a lot of work in simplifying the configuration and removing all of the boilerplate. Additionally, if you are securing the server with Keycloak, accessing the console will correctly obtain credentials through the realm login page.

Non-blocking internals

Our quest to make better use of the available hardware resources in all deployment models (bare-metal, containerized, virtualized) continues as we’ve now consolidated a lot of thread-pools into just two: non-blocking and blocking. Most of the code now makes use of the non-blocking pool. Paths which may block, such as certain persistent stores, use the blocking pool so that they don’t hold up work that may be processed without blocking. This release also includes a new non-blocking Store SPI, so that you can take advantage of stores with real non-blocking I/O.


As Infinispan is participating in CloudButton, a Serverless Data Analytics Platform which is part of the European Union’s Horizon 2020 research and innovation programme, we have introduced a new optional feature which allows scaling by adding new nodes to a cluster without state-transfer. This means that you can add capacity with zero-impact to your operations. Obviously this comes at the cost of reduced resilience in case of failures, but, for scenarios where high availability is not required, this gives you a highly scalable in-memory storage solution.

If high availability is your thing, the rebalancing algorithm which decides how segments (our subdivision of the data space) are mapped to nodes has been overhauled to be much more accurate and fairer.


Querying and indexing will be the major focus in Infinispan 12 (with the long awaited upgrade to Hibernate Search 6 and Lucene 8). In preparation for that, a lot of work has gone into deprecations, usability, clean ups and documentation.

Hot Rod Client improvements

Many usability changes have been added to our Java Hot Rod client:

  • a Hot Rod URI as a compact way to configure a connection

  • automatic creation of caches on demand using supplied configurations/templates with support for wildcards

  • improved iteration of entries by concurrently splitting work across segments/nodes

Other Server changes

If you are using the JDBC cache store to persist your cache entries to a database, Infinispan Server now restores the ability to create shared datasources which was lost when we abandoned the WildFly base.


The CLI received a number of new features such as logging manipulation, obtaining sever reports and user management, superseding the user-tool script.



Our console overhaul, which started in 10, continues with lots of new features, integrations and polishing. Highlights are:

  • entry creation dialog box

  • querying

  • KeyCloak integration


Clouds, containers and operators

Our Infinispan Server image is now based on ubi-minimal:8.2.

And thanks to our friends over at Quarkus, Infinispan Server is now also available as a native image built using GraalVM. This image is available on and Docker Hub.

The Kubernetes Operator adds a new Cache Custom Resource and the ability to expose services via Ingress and Routes.


Documentation has also received a lot of love in all areas:

  • Added procedural content for rolling upgrades, Cache CR with the Operator, server patching, misc CLI commands, using RemoteCacheConfigurationBuilder.

  • Procedural content for different upgrade and migration tasks included in Upgrade Guide.

  • Operator and Spring Boot Starter guides now provide stable and development versions from the index page.

  • Updated index.html and throughout documentation to improve high-level context and aid retrievability.

  • Getting Started content updated and streamlined.

  • Applied several modifications, additions, and removals to documentation via community feedback.

What’s next ?

As briefly mentioned above, Infinispan 12 will be our next release, scheduled for this autumn. We will be working on query/index improvements, backup/restore capabilities as well as the usual load of improvements, clean-ups across the board. We will keep you posted with development release and blogs about upcoming highlights. If you’d like to contribute, just get in touch.

Infinispan 11.0.0.CR1

Dear Infinispan community,

we’ve just released 11.0.0.CR1 which comes loaded with quite a few features and improvements.

Cross-Site Replication Improvements

The cross-site replication feature received two major improvements:

  • Support for multiple site masters

    The new algorithm is able to take advantage of multiple site masters, distributing load between them. If your environment is capable, increase the number of site masters in RELAY2 configuration:

    <relay.RELAY2 site="LON" max_site_masters="1000"/>
  • Conflict detection and resolution for Asynchronous Cross-Site Replication

    Taking advantage of vector clocks, in asynchronous mode, Infinispan is able to detect conflicts. A conflict happens when 2 or more sites update the same key at the same time. Conflicts are resolved based on the site’s names. Updates from the site lexicographically lower, take priority, in case of conflicts. As an example, if you have 3 sites, LON, NYC and SFO, conflicts between LON and NYC discards updates from NYC and keeps the updates from LON. You can choose the priority by prepending a number to the site name. For example, if you want updates from NYC to take priority, you can set the site name to “1-NYC”.

In a future update, Infinispan will allow you to set a custom conflict resolution algorithm.

Non-blocking internals

  • All thread pools collapsed into two pools: blocking and non-blocking


  • A new non-blocking Store SPI


  • More accurate segment rebalancing

  • Scaling without state-transfer (experimental)


  • SearchManager, CacheQuery are deprecated. Users are encouraged to migrate to Ickle String queries obtained from Search.getQueryFactory

Server Security

  • The server is now secure by default

  • New encrypted properties realm

  • Simplified authentication and authorization configuration to be as automatic as possible

Other Server changes

  • Datasources

  • Runtime logging configuration

  • Server report


  • User Tool merged into CLI

  • CLI can be compiled natively

  • Non-interactive usage


  • Lots of UX improvements

Kubernetes/OpenShift operator

  • Cache CR

  • Service .Expose with Ingress and Route

Container images

  • Images based upon ubi-minimal:8.2

  • Native generation of config files in all images

  • Native server image available at infinispan/server-native (Experimental)


  • Added procedural content for rolling upgrades, Cache CR with the Operator, server patching, misc CLI commands, using RemoteCacheConfigurationBuilder.

  • Procedural content for different upgrade and migration tasks included in Upgrade Guide.

  • Operator and Spring Boot Starter guides now provide stable and development versions from the index page.

  • Updated index.html and throughout documentation to improve high-level context and aid retrievability.

Infinispan 11.0.0.Alpha2 and 10.1.3.Final

Dear Infinispan community,

we’ve just tagged a couple of releases.

First off is the second Alpha release of what will eventually become Infinispan 11. The release notes may not be exciting, but it is mostly preparatory work for the big features we are working on: vastly improved async cross-site replication, monitoring, query improvements, the console and the CLI, and more.

We also released a micro-update to 10.1 which fixes quite a few bugs, especially in the way we handle JMX and MP metrics and further improves the documentation.

New release naming scheme

Starting with the next development release of Infinispan 11, we will be adopting a new naming scheme. We will no longer be using the Alpha and Beta monikers, but we will use a progressive Dev suffix to indicate that it’s a development release. The next release will therefore be called 11.0.0.Dev03.

Infinispan Spring Boot Starter released with Spring Boot 2.2.4.RELEASE

Dear Infinispan and Spring Boot users,

We are pleased to announce the release of Infinispan Spring Boot  2.1.8.Final and 2.2.0.Final.

2.1.8.Final uses Infinispan 9.4.17.Final and Spring Boot 2.2.2.RELEASE

2.2.0.Final uses Infinispan 10.1.1.Final and Spring Boot 2.2.2.RELEASE 

Configuring Marshalling with Infinispan 10.x

Infinispan 10.x servers have some significant changes to marshalling that impact Spring Boot users.

The default Marshaller for Infinispan 10.x is ProtoStream, which uses Protocol Buffers to provide extensible, language and platform neutral serialization.

Unfortunately ProtoStream does not currently work with Infinispan Spring Cache and Session support. As a result, Spring users in Remote Client/Server Mode must use the Java Serialization Marshaller and add classes to a Java serialization whitelist.

Add the following configuration properties:


The property specifies the classes, or packages, that Java serialization can marshall. Separate multiple class names with a comma (,).

Note that, in previous versions, JBoss Marshaller was the default for Infinispan. Spring users can also use JBoss Marshalling, but it is deprecated as of Infinispan 10.x.

Get it, Use it, Ask us!

You can find these releases in the maven central repository.

Please report any issues in our issue tracker and join the conversation in our Zulip Chat to shape up our next release.

Infinispan Operator 1.1.0 is out!

We’re pleased to announce version 1.1.0 of the Infinispan Operator for Kubernetes and OpenShift.

This release includes a bunch of very exciting features! Let’s dig into them:

Full Lifecycle

Infinispan Operator 1.1.0 is rated at the Full Lifecycle capacity level, which means the Operator now provides advanced cluster management capabilities and functionality to handle demanding workloads.

One of the key new features in this release is graceful shutdown, which lets you bring clusters down safely to avoid data loss.

During cluster shutdown, caches can passivate in-memory entries to persistent storage along with the internal Infinispan state that maps which nodes own which entries. When you bring Infinispan clusters back, all your data is restored to memory.

Check out the Graceful Shutdown docs for more information.

Graceful shutdown also enables the Infinispan Operator to perform reliable upgrades.

When a new version of the Infinispan Operator starts, it checks for running Infinispan clusters that were created by an older Operator version.

If the Operator detects a cluster that requires upgrade, it invokes a graceful shutdown on the cluster and then brings it back with the new Infinispan version.

You can perform upgrade manually or automatically with the Operator Lifecycle Manager on OpenShift.

Note that Operators installed via the OperatorHub on OpenShift Container Platform are managed by the Operator Lifecyle Manager.

Cache vs DataGrid

This version of the Infinispan Operator delivers Cache and DataGrid services.

By default the Operator starts Infinispan clusters as Cache services, which provides a quick way to set up in-memory caching that stores data off-heap and keeps single copies of data in the cluster.

DataGrid services, on the other hand, are suited to more advanced use cases where you control and define the configuration that you need.

Cross-Site Replication

The Infinispan Operator simplifies cross-site replication set up with DataGrid services so you can back data up between separate Kubernetes or OpenShift clusters.

All you need to do is specify which type of external Kubernetes service to expose, the list of all backup locations, access secrets, and the local site name.

Find out more at: Cross-Site Replication

Automatic TLS configuration

If you’re running on Openshift and have a service that serves certificates, the Operator automatically asks for certificates sets up TLS for your endpoint connections. Encrypted by default with zero effort!

Get it, Use it, Ask us!

Try the simple tutorial for the Operator, which has been updated for this version. The tutorial shows how to install the Operator manually, but it can also be installed via the Operator Hub on OpenShift.

You can report bugs, chat with us, ask questions on StackOverflow.

Infinispan 10.1.0.Final

Hi there,

we finish 2019 in style with the Final release of Infinispan 10.1, codenamed "Turia".

Server console

The highlight of this release is the new server console which is now based on Patterfly 4 and React.js. We will soon have a blog post detailing the work that has been done and our future plans. In the meantime, here are a few screenshots:

Welcome Page
Console Caches
Console Cache Stats


Many changes related to security have happened since 10.0:

  • Native SSL/TLS provided by WildFly OpenSSL. The server only ships with native libraries for Linux x86_64, but you can download natives for other platforms and architectures

  • Improved usability of the Hot Rod client configuration with better defaults

  • Full support for authorization for admin operations via the RESTful endpoint

  • Console authentication support

  • Kerberos authentication for both Hot Rod (GSSAPI, GS2) and HTTP/Rest (SPNEGO)

  • Improved LDAP realm configuration with connection tuning and attribute references

  • Rewritten client/server security documentation including examples on how to create certificate chains, connecting to various LDAP directories and KeyCloak, etc.


  • A command-line switch to specify an alternate logging configuration file

  • Query and indexing operations/stats are now exposed over the RESTful API

  • Tasks and Scripting support

  • Support for binding the endpoints to / ::0 (aka INADDR_ANY)


More work has landed on the quest to completely remove blocking calls from our internals. The following have been made non-blocking:

  • State transfer

  • The size operation

  • Cache stream ops with primitive types

Additionally caches now have a reactive Publisher which is intended as a fully non-blocking approach to distributed operations.


  • The query components have been reorganized so that they are more modular.


  • The introduction of histogram and timer metrics.

  • The /metrics endpoint now includes base and vendor microprofile metrics


  • The REST cache store has been updated to use the v2 RESTful API.

Removals and deprecations

  • The old RESTful API (v1) has been partially reinstated until 11.0. Bulk ops are disabled.

  • The Infinispan Lucene Directory has been deprecated.

  • The memcached protocol server has been deprecated. If you were relying on this, come and talk to us about working on a binary protocol implementation.

Bug fixes, clean-ups and documentation

Over 160 issues fixed including a lot of documentation updates. See the full list of changes and fixes
