Infinispan 10.0.0.Beta4

Dear Infinispan users,

it has been a while since our last release and quite a few things have been cooking in the Infinispan furnace. Bear in mind that the list below should just serve as a summary and that dedicated blogs, documentation and examples will appear in the near future.

Server

Since 5.3, our server has been built on top of WildFly (JBoss AS7 at the time). WildFly gave us a very solid base, including integration with a lot of useful components (security, datasources, management etc) but it also forced us to maintain a large amount of integration code. We have therefore decided to start from a much leaner base to build the new server which, internally we've been calling ServerNG, but which we're now releasing as "Infinispan Server". The old WildFly-based server is still available, but it should be considered "legacy" and will no longer receive any feature enhancements.

The new server deserves its own dedicated post, but its main features are:

• smaller size (36MB vs 130MB)
• smaller memory footprint (20MB heap usage at boot vs 40MB)
• single-port: the Hot Rod, REST and management endpoint are now served through a single-port (11222) with automatic protocol detection between HTTP/1.1, HTTP/2 and Hot Rod. The memcached endpoint is handled separately since we don't implement the binary protocol yet.
• security implemented using WildFly Elytron currently supporting PLAIN, DIGEST-MD5, SCRAM, EXTERNAL mechs for Hot Rod, BASIC, DIGEST, CLIENT_CERT for REST/HTTP (OAuth/JWT/GS2/GSSAPI/SPNEGO will be coming in the next releases)
• the server configuration extends the embedded configuration scheme
• caches/counters are created and managed dynamically through Hot Rod / REST.

Marshalling

Infinispan's marshalling has received a significant overhaul and it is now split into three distinct marshallers: Internal, Persistence and User (ISPN-7409 ISPN-9621)
The Persistence marshaller is now based on ProtoBuf allowing for long-term compatibility of data stored in memory and in cache stores.
The Store Migrator has been updated to allow migration from Infinispan 8.x/9.x cache stores to the new format (ISPN-10276)

Core changes

Infinispan's internal dependency-injection has been completely rewritten so that factories, components and dependencies are discovered and resolved at compile time instead of using runtime reflection. This, together with the marshalling changes and recent JGroups changes, paves the way for usage and native compilation with Quarkus.

REST

The REST API is continuing its overhaul with the following additions to the v2 API

• Cluster Resource (ISPN-10268)
• Cache Resource (ISPN-9772 ISPN-10392)
• Counter Resource (ISPN-10151 ISPN-10152)

The REST endpoint now fully supports authorization (ISPN-8736)

Reactive API

The first implementation of our new Reactive API have been merged. This is still work in progress and the API will receive major changes until the Final release.
The new API includes a new API module and a new KeyValueStore Hot Rod client where search, continuous search and Key Value store methods are included.

Cross-Site Replication

Async mode cross-site replication received 2 major improvements:

• async mode is now able to detect disconnections between sites and bring the site offline based on <take-offline> configuration (ISPN-10180)
• track and exposes the average replication times for asynchronous requests (ISPN-9457)

Non-blocking

• Non-blocking Hot Rod authentication (ISPN-9841)
• Non-blocking REST endpoint (ISPN-10210)
• Update internal remote listener code to support non blocking (ISPN-9716)
• Update internal embedded listeners to be non blocking (ISPN-9715)

Removal/deprecations

A new major release is also an opportunity to do some house cleaning.

Deprecations

• Deprecate GridFileSystem and org.infinispan.io stream implementations (ISPN-10298)
• Deprecated Total Order transaction mode (ISPN-10259)

Removals

• AtomicMap implementations removed (ISPN-10230)
• Remove deprecated org.infinispan.io classes (ISPN-10297)
• Remove org.infinispan.tools.ConfigurationConverter (ISPN-10231)
• Remove compatibility mode (ISPN-10370)

If you are curious you can read the detailed release notes including all fixed issues.
As usual you can ask questions on the forum, StackOverflow and interactively on our Zulip Chat.
Please report any bugs you find on our Issue Tracker.
Going back to our three-week schedule, our next release will be Beta5, three weeks from now.

Infinispan 10.0.0.Beta2 and 9.4.8

Hello Infinispan users,

What ? You're wondering where Beta1 is ? And what happened to 9.4.7 ?
Unfortunately, those releases, while tagged and available on your closest Maven Central mirror will only work with Java 11, so we had to rebuild and re-release.

So, without further ado, I give you 10.0.0.Beta2 and 9.4.8.Final.

The first change I should outline is one that will impact you if you are building Infinispan from source. The previous build structure required having both JDK 8 and JDK 11 in order to compile a release which worked on both. In order to simplify the build process, as well as ensuring that the output is always consistent we now require Java 11 only. Don't worry: the resulting binaries will still work on Java 8 and greater.

10.0.0.Beta2

The first beta of our next major release contains a number of enhancements:

[ISPN-9847] - Extend configuration to allow inline JGroups configuration and inheritance
[ISPN-9699] - Cluster member owning no data
[ISPN-8124] - ServerNG: Initial implementation

We will soon be posting about these features individually.

The work on persistent storage long-term compatibility is progressing with
[ISPN-9845] - Stop exposing InternalMetadata via the persistence SPI

Notable fixes:

[ISPN-4075] - State transfer should preserve the creation timestamp of entries

And if you were still using the old Distributed Executor, that has been finally removed in
[ISPN-9784] - Remove Distributed Executor

9.4.8.Final

Our latest point release contains lots of bug fixes and minor enhancements.

As usual you can ask questions on the forum, StackOverflow and interactively on our Zulip Chat.
Please report any bugs you find on our Issue Tracker

Dear Infinispanners,
C++ and C# 8.2.0.Beta1 releases are available!

These releases contain all the 8.2.0 features.

Worth a mention is the improvement in the remote execution API: we moved the JBossMarshaller basic implementation from test to the distro in order to simplify the data management on the application side. Test examples [1] and [2] have been updated accordingly.

Next step will be a CR release containing improvements on API docs (doxygen)

Infinispan 9.0.0.Beta1 "Ruppaner"

It took us quite a bit to get here, but we're finally ready to announce Infinispan 9.0.0.Beta1, which comes loaded with a ton of goodies.

• Performance improvements
• JGroups 4
• A new algorithm for non-transactional writes (aka the Triangle) which reduces the number of RPCs required when performing writes 
• A new faster internal marshaller which produced smaller payloads. 
• A new asynchronous interceptor core
• Off-Heap support
• Avoid the size of the data in the caches affecting your GC times
• CaffeineMap-based bounded data container
• Superior performance
• More reliable eviction
• Ickle, Infinispan's new query language
• A limited yet powerful subset of JPQL
• Supports full-text predicates
• The Server Admin console now supports both Standalone and Domain modes
• Pluggable marshallers for Kryo and ProtoStuff
• The LevelDB cache store has been replaced with the better-maintained and faster RocksDB 
• Spring Session support
• Upgraded Spring to 4.3.4.RELEASE

We will be blogging about the above in detail over the coming weeks, including benchmarks and tutorials.

The following improvements were also present in our previous Alpha releases:

• Graceful clustered shutdown / restart with persistent state
• Support for streaming values over Hot Rod, useful when you are dealing with very large entries
• Cloud and Containers
• Out-of-the box support for Kubernetes discovery
• Cache store improvements
• The JDBC cache store now use transactions and upserts. Also the internal connection pool is now based on HikariCP

Also, our documentation has received a big overhaul and we believe it is vastly superior than before.

There will be one more Beta including further performance improvements as well as additional features, so stay tuned.

Infinispan 9 is codenamed "Ruppaner" in honor of the Konstanz brewery, since many of the improvements of this release have been brewed on the shores of the Bodensee !

Prost!

Infinispan 8.2.0.Beta2 and 8.1.2.Final

Dear Infinispan community,

we're proud to announce two fresh releases today.
First off is 8.2.0.Beta2, from our development branch. It is packed with a bunch of goodies:

• lots of enhancements and additions to the administration console for Infinispan Server, such as cluster event views, task management, container administration and deployments. Some of these will be further refined before the upcoming Final release. If you prefer to manage your servers from the good ol' command-line, the CLI commands have also been similarly enhanced.
• performance improvements for clustered reads, bulk and stream ops, and a sensible reduction in memory allocation rate. More improvements will come as we are rewriting some parts of the core to allow further optimizations.
• a new distributed executor, ClusterExecutor which does not require an existing distributed cache and which comes complete with Java 8 goodness such as CompletableFutures and lambda support. This nicely complements our existing Streams support.
• a new, experimental index manager to store indexes on Infinispan with better scalability and indexing throughput. Additionally we've upgraded Lucene to 5.4.1 and Hibernate Search to 5.6.0.Alpha1
• the ability to indicate a number of nodes for initial cluster formation
• lots of bug fixes

We're still on track for a Final release at the end of the month.

We've also been fixing bugs in our stable 8.1 stream, which means we have a freshly released 8.1.2.Final.

Check out the development release notes, the stable release notes, download the releases and tell us all about it on the forum, on our issue tracker or on IRC on the #infinispan channel on Freenode.

Infinispan 8.2.0.Beta1 and 8.1.1.Final are out!

Dear all,

We are proud to announce two releases today:

Infinispan 8.2.0.Beta1 is the first release in the 8.2 cycle. It doesn't have big new features, but there are a few significant changes in addition to the usual bug fixes:

• SyncConsistentHashFactory is now the default consistent hash factory (ISPN-4851). This means the owners of a key are going to be the same in all the caches, as long as the caches have the same members and the same number of owners.
• We now have a new way for applications to determine the location of keys: the KeyPartitioner interface (ISPN-5465). In spirit it is very similar to the existing Grouper interface, but it is segment-aware. Note that none of the HotRod clients support Keypartitioner in this release.
• We improved the rolling upgrade performance (ISPN-6046).
• We added a new event logger that records cluster membership, cache topology, and cache availability changes (ISPN-5816). In the next release, it will also be accessible through the server's management console.

Infinispan 8.1.1.Final includes a number of bug fixes. All users of 8.1.0.Final are encouraged to upgrade.

You can get both releases from our download page. If you are new to Infinispan, you can learn how to use it, and help us continually improve it.

Infinispan 8.1.0.Beta1

Dear all,

The first Beta release of Infinispan 8.1 is now available for use.  Our new admin console has gone through quite a lot of changes recently.  As mentioned before the new console allows for administration of Infinispan cluster nodes and now we would like to show some screenshots of a running server in the below gallery.

We would greatly appreciate your feedback regarding the admin console web application, let's shape it together!

For all other improvements as well as bug fixes you can see the release notes. Infinispan 8.1 Final is still on track for the end of this month. If you are new to Infinispan you can learn how to use it, and help us continually improve it.

Infinispan 8.0.0.Beta1

Dear Infinispan community,

It is with great pleasure that we are announcing the first Beta release of Infinispan 8.0.0.

These are the main changes in this release:

• Support for mixed queries, accessing both indexed and non-indexed fields.
• Server rebased on WildFly 9.0.0.CR2.
• HotRod Java client API exposing the mapping of segments to servers.
• Preventing inconsistencies when the cluster splits during transaction commit.
• Fixes for a bunch of bugs in our write-behind store support, contributed by Karsten Blees.
• And even more bugfixes, please read the release notes for the whole list.

Download it now and tell us what you think on our forums or come and meet us on IRC: channel #infinispan on Freenode. Don't forget to also check-out our roadmap to see the things we plan to get done during the 8.0 cycle.

Many thanks to all who contributed to this release!

Infinispan 7.2.0.Beta2 released with better default configuration handling

We've just released Infinispan 7.2.0.Beta2 which adds better support for determining which configuration options have been defined by the user versus those options that contain default values. This is an important stepping stone in our aim to enable partial configuration overlays and proper configuration template support.

On top of that, we've added the capability for Java Hot Rod clients to recover from full cluster restarts and fixed an important topology transfer bug that lead to ArrayIndexOutOfBoundsException exceptions when applying topology changes.

Finally, in order to provide better out-of-the-box experience with Near Caches in Java Hot Rod client, we have made mandatory to define the maximum number of entries Near Caches should have. Previously, Near Caches were configured to be unbounded by default which would have resulted in memory leaks unless the client removed them by calling RemoteCache.remove() or similar. A configuration exceptions is reported now if no maximum size has been defined in the Java Hot Rod client, but the user can still provide a 0 or negative value to indicate the Near Caches should be unbounded.

For a complete list of features and bug fixes included in this release, please refer to the release notes.  

Feel free to join us and shape the future releases on our forums, our mailing lists or our #infinispan IRC channel.

Cheers,

Galder

Infinispan 5.3.0.Beta2 is out!

The highlights of this release are:

• interoperability between Hot Rod, Memcached, REST and embedded mode. E.g. it is now possible to write data through an REST interface and read it through Hot Rod or the other way around
• the ability to expose the same container over multiple Hot Rod endpoints and the integration of the WebSocket endpoint

Please stay tuned for blogs detailing these features.

For a complete list of features included in this release refer to the release notes.

Infinispan 5.2.0.Beta6 is out!

5.2.0.Beta6 brings a new batch of fixes around Non-Blocking State Transfer, Map/Reduce and command line interface.
But it's not only that, it also brings a bran new pice of functionality: support of concurrent updates for non-transactional caches(ISPN-2552) . Prior Infinispan 5.2.0.Beta6, there was a high chance for a deadlock to occur when two threads concurrently update the same key. This caused significant performance costs and throughput degradation, linear to the amount of contention. This functionality is enabled by default even though a compatibility mode is still available. You can read more about it here.


For a detailed list of all the issues fixed please refer the release notes.

You can download the distribution or the maven artifact. If you have any questions please check our forums, our mailing lists or ping us directly on IRC!

Infinispan 5.2.0.Beta5

Hi Infinispan users,

5.2.0.Beta5 contains the usual batch of fixes especially around Non-Blocking state transfer functionality, Map Reduce and the CLI.

Functionality-wise, it is now possible to read/write data concurrently to the same remote cache both via a RemoteCacheManager and a RemoteCacheStore by enabling "rawValues" in the latter. This is the final item that was needed to enable us to implement Rolling Upgrades for remote caches. Because of this feature the HotRod protocol required a couple of extensions and therefore its version has been bumped to 1.2

For a detailed list of all the issues fixed please refer the release notes.

You can download the distribution or the maven artifact. If you have any questions please check our forums, our mailing lists or ping us directly on IRC!
