Introducing LevelDB Cache Store

Infinispan 5.3.0 will be introducing a LevelDB cache store.  This cache store will allow you to store cache entries using a fast filesystem based LevelDB key-value store originally developed by Google.  This cache store uses a Java implementation of LevelDB, and maybe one day, it can get even better performance by using the JNI implementation.

Configuration is simple:
Please see documentations for detailed sample usage and configuration.

Hope you enjoy this new addition!

Using MongoDB as a cache store

With the 5.3 release, there is a brand new feature. I'm glad to announce that you will be able to use MongoDB as a cache store.

For those who don't know MongoDB, it's an open-source document oriented NoSQL database developped by 10Gen. You can more information about it on http://www.mongodb.org/.

The question you have right now, it probably, how to use it cool cache store ? Simple, as for the other cache store you have to add a loader in your Infinispan configuration file.

Here is an exemple:

If you prefer the programmatic API:
For more information about the configuration possibilities (default values, options, etc) , you can refer to the documentation page

Introducing JPA Cache Store

Good news everyone - Infinispan 5.3.0 will be introducing a long awaited JPA cache store.  This cache store will allow you to store cache entries in the database using proper schema - so that other applications can read the persisted data as well.

In normal use cases, it's recommended to leverage Infinispan as JPA second level cache and/or query cache. However, if you'd like to use only Infinispan API and you want Infinispan to read from database, or to persist the data into a database with well defined schema, then JPA cache store could be right for you.

Prior to JPA cache store, those who wants to use Infinispan in front of a database to read/write database records would need to write their own cache store implementation.  Now, with JPA cache store, users can use Infinispan in front of a database (write-through or write-behind) with ease by using standard JPA mapping and configurations.

To use the cache store is simple - create the standard JPA configuration (persistence.xml) and entity class, and then configure the cache store:

Please see documentations for detailed sample usage and configuration.

Hope you enjoy this new addition!

Infinispan 5.3.0.CR1 is out!

Besides a handful of fixes, this release contains two very important contributions:

• a mongoDB cache store which allows using Infinispan  as a cache on top of a mongodb instance. Courtesy of  Guillaume Scheibel
• a JPA based cache store that allows an easy setup for Infinispan as a cache in front of a database. Courtesy of Ray Tsang

Please stay tuned for blogs detailing these features.

Infinispan to adopt the Apache Software License

Starting with Infinispan 6.0, the project will move from its current GNU Lesser General Public License (LGPL) v.2.1 licence to the Apache License (AL) v.2.0.
The switch from the weak copyleft LGPL license to the more permissive AL one is in response to continued requests from the wider open source community who intend to integrate Infinispan into open source projects that aren’t LGPL-friendly.  A more permissive license broadens Infinispan’s community, ecosystem and general appeal.

To deal with any concerns you may have, I've put together some FAQs below:

Is it still open source?

Yes.  The source code for Infinispan is and always will be open and freely accessible.

Is it as business-friendly?

The AL is often regarded as more business-friendly than LGPL.

How does that affect our existing users?

It doesn't.  You are just as free to use, contribute, and participate in the project.

How does that affect our contributors?

In accordance with the JBoss Contributor License Agreement, all past contributions to Infinispan will be re-licensed to the AL.  Future contributions will be licensed under the AL too.

This relicensing is part of our ongoing effort to build and maintain a strong and inclusive open source community, and I hope you're on our side with this move.

Feel free to post any questions or thoughts as comments on this blog.

Thanks

Interoperability between Embedded and Server Endpoints is here!

As mentioned by Mircea in the Infinispan 5.3.0.Beta2 release blog post, interoperability between embedded Infinispan and remote Infinispan modes, including Hot Rod, Memcached and REST is now here!

What this means is that you should be able to store data via one of the endpoints and retrieve data from a different one. So, I can store an Java object using the Java Hot Rod client, and I can retrieve it using the embedded interface.

Documentation for this new interoperability, or compatibility mode, can be found here, including the key aspects of this new functionality, configuration and links to some examples.

As we head towards the later part of the Infinispan 5.3 series, if you're interested in accessing data in multiple ways, give it a go and let us know what you think!

Cheers,
