Dear all,

The second Alpha 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.

Cheers! Will

Dear all,

release early release often ! The first Alpha release of Infinispan 8.1 is out. As is traditional, it is codenamed after a beer. This time it is "Mahou" !

The highlights for 8.1.0.Alpha1 are:

Read the complete release notes 

We’re working on lots of cool things for 8.1 Final due at the end of November, so be sure to check our roadmap to see what’s coming.

Get it, learn how to use it, help us improve it.

Enjoy !

Dear Infinispan community,

it is with great pleasure that we are announcing the release of Infinispan 8.0.0.Alpha2 as we continue forward.

This release brings a few very useful features:

Don’t forget to also check-out our roadmap to see the things we plan to get done during the 8.0 cycle.

Download it now and tell us what you think on our forums or come and meet us on IRC: channel #infinispan on Freenode.

Dear Infinispan community,

it is with great pleasure that we are announcing the release of Infinispan 8.0.0.Alpha1. This is the first release of Infinispan that requires Java 8 to compile and run. We have great plans in store for our Java 8 API, and this is the first step in getting there. Don’t worry, however: we intend to maintain backwards compatibility for both configuration and API.

This release brings some highly requested features:

We have also removed asynchronous marshalling which never worked quite right, and also imposed several limitations on applications. Good riddance !

Don’t forget to also check-out our roadmap to see the things we plan to get done during the 8.0 cycle.

Download it now and tell us what you think on our forums or come and meet us on IRC: channel #infinispan `on Freenode. `

Infinispan HotRod C# Client 7.0.0.Alpha1 is now available. This new version is a C# wrapper over the native client and brings support for L2 and L3 client intelligence levels in addition to L1. As more features are added to the native client they will make their way into the C# client as well.

You can find the the .msi installer on the download page and the source code on GitHub. Please give it a try and let us know what you think.

Infinispan 6.0.0.Alpha4 is now with a few very important changes, particularly around cache stores. We’ve completely revamped the cache store/loader API to align it a bit better with JSR-107 (old CacheStore has become CacheWriter) and to simplify creation of new implementations. The new CacheLoader and CacheWriter should help implementors focus on the important operations and reduce the coding time. We’ve also created AdvancedCacheLoader and AdvancedCacheWriter in order to separate for bulk operations or purging for those implementations that wish optionally implement them. Expect a blog post from Mircea in the next few days providing many more details on this topic.

This new Infinispan version comes with other important goodies:

As announced yesterday by Adrian, the brand new Infinispan 6.0.0.Alpha1 release contains a new file-based cache store which needs no extra dependencies. This is essentially a replacement of the existing FileCacheStore which didn’t perform as expected, and caused major issues due to the number of files it created.

The new cache store, contributed by a Karsten Blees (who also contributed an improved asynchronous cache store), is called SingleFileCacheStore and it keeps all data in a single file. The way it looks up data is by keeping an in-memory index of keys and the positions of their values in this file. This design outperforms the existing FileCacheStore and even LevelDB based JNI cache store.

The classic case for a file based cache store is when you want to have a cache with a cache store available locally which stores data that has overflowed from memory, having exceeded size and/or time restrictions. We ran some performance tests to verify how fast different cache store implementations could deal with reading and writing overflowed data, and these are the results we got (in Ks):

The difference is quite astonishing but as already hinted, this performance increase comes at a cost. Having to maintain an index of keys and positions in the file in memory has a cost in terms of extra memory required, and potential impact on GC. That’s why the SingleFileCacheStore is not recommended for use cases where the keys are too big.

In order to help tame this memory consumption issues, the size of the cache store can be optionally limited, providing a maximum number of entries to store in it. However, setting this parameter will only work in use cases where Infinispan is used as a cache. When used as a cache, data not present in Infinispan can be recomputed or re-retrieved from the authoritative data store and stored in Infinispan cache. The reason for this limitation is because once the maximum number of entries is reached, older data in the cache store is removed, so if Infinispan was used as an authoritative data store, it would lead to data loss which is not good.

Existing FileCacheStore users might wonder: what is it gonna happen to the existing FileCacheStore? We’re not 100% sure yet what we’re going to do with it, but we’re looking into some ways to migrate data from the FileCacheStore to the SingleFileCacheStore. Some interesting ideas have already been submitted which we’ll investigate in next Infinispan 6.0 pre-releases.

So, if you’re a FileCacheStore user, give the new SingleFileCacheStore a go and let us know how it goes! Switching from one to the other is easy :)

Cheers,

Galder
