The road to Infinispan 10 (Alpha1)

Dear all,

Today we are releasing 10.0.0.Alpha1 and 9.4.2.Final.

Infinispan 9.4.2.Final comes with a number of bug fixes and some small additional features:

  • ISPN-9655 REST Access Log headers
  • ISPN-8144 & ISPN-9661 Cross-Site replication statistics
  • ISPN-9708 Expose the executor services through JMX
  • ISPN-9732 Local iteration optimization with write behind is valid for non shared stores
  • ISPN-9717 Fix Integer overflow for lifespan and maxIdle

We have begun working on what will become Infinispan 10. As with all new major releases, this will come with a number of important changes.

  • New Server
    We are working on a new lightweight server, currently dubbed ServerNG, which will supersede the current WildFly-based offering. The new server will have a smaller disk and memory footprint, a new RESTful admin interface, improved security. It will still use familiar components (Elytron for security, Narayana for transactions, etc) but we hope that the installation and usability experience will be most improved. A dedicated blog post will describe in detail what is coming.
  • Long-term Storage Format
    The persistent storage format will be changed so that it will be easier to transparently make changes to it without requiring further exporters/importers.
  • Non-blocking listeners
    The listener implementation will be replaced with a non-blocking implementation.
  • Asynchronous CacheLoader/Store
    Store operations will be ran in another thread to provide non blocking for main threads
  • Improved statistics
    Infinispan statistics have been traditionally over-simplistic, offering mostly basic averages for writes and reads. We are going to implement percentiles on a histogram as well as recording tracing information so that you will be able to know how much time is being spent in the various subsystems (clustering, persistence, etc.)
  • New API
    The current Infinispan API, based around Java's ConcurrentHashMap design, does not offer the flexibility required to support modern reactive designs as well as the various extensions we've added over the years (counters, multimaps, etc). We are therefore working on a new modern API design which we will be describing with a number of blog posts in the near future.
  • Agroal JDBC Connection Pool
    We are replacing the JDBC connection pool implementation with Agroal.
  • Kubernetes Operators
    Operators are all the rage in the Kubernetes world, and we are working on an Infinispan Operator which will take care of managing and monitoring the health of an Infinispan cluster, handle scale up/scale down safely, perform upgrades and more.

Infinispan 10.0.0.Alpha1 is the first release from our development branch. It currently includes the following features on top of what is in 9.4.2.Final:

Quick start Infinispan on Kubernetes

Last week we showed you how to easily run Infinispan on top of OpenShift. This week we're trying to do the same on Minikube, a tool that makes it easy to run vanilla Kubernetes locally.

Although we've already covered the topic in the past, we felt the descriptors needed a permanent location and an update to the latest Infinispan releases. Detailed instructions can be found in this repository.

With OpenShift, we took advantage of Templates which allow a set of objects to be parameterised.
Templates are OpenShift specific, so Kubernetes does not understand them. Instead, we provide you with the individual descriptors required to run Infinispan (Helm chart to come...). This includes:


Before applying the descriptors, download and install Minikube. Then, set a profile, select the VM driver, give it enough CPU and memory for your experiments, and start it.

Once Minikube it's running and you have the corresponding kubectl command line tool installed, simply call:

$ kubectl apply -f .

Once all pods are ready, you should verify the 3-node cluster has formed correctly (find out how in the README file).

When ready, you can start storing and retrieving data. The HTTP REST endpoint is particularly useful for these initial tests, to verify everything works as expected:

$ kubectl exec \
  -it infinispan-server-0 \
  -- curl -v -u test:changeme -H 'Content-type: text/plain' -d 'test' infinispan-server-http:8080/rest/default/stuff

Then:

$ kubectl exec -it infinispan-server-1 \
  -- curl -v -u test:changeme infinispan-server-http:8080/rest/default/stuff

Go and try it out and let us know what you think. You can find us on this Zulip chat :)

The fastest path to running Infinispan on OpenShift!

Creating an Infinispan Server cluster in OpenShift has never been easier! We've just given the OpenShift templates for Infinispan server their biggest makeover yet which should help both Infinispan and OpenShift users:

The repository has been simplified and flattened out to only leave essential information. Minishift is the preferred way to get started with Infinispan and OpenShift, so we've tailored the instructions for this set up.

OpenShift templates are now YAML based which is less verbose, but more importantly, allows Infinispan Server XML configuration to be shown as-is. This makes it easier to directly modify the XML in the template itself.

The fastest way to get started with Infinispan and OpenShift is to simply fire up Minishift, set a profile, checkout our Infinipan OpenShift repository and then call:

oc create -f infinispan-ephemeral.yaml
oc new-app infinispan-ephemeral

These two simple steps will get you a single node Infinispan Server running! A more detailed getting started guide can be found in the repository's README file.

Go and try it out and let us know what you think. You can find us on this Zulip chat :)

Cheers,
Galder
