Introduction Welcome to the official Infinispan user guide. This comprehensive document will guide you through every last detail of Infinispan. Because of this, it can be a poor starting point if you are new to Infinispan. For newbies, starting with the Getting Started Guide or one of the Quickstarts is probably a better bet.
The Frequently Asked Questions and Glossary are also useful documents to have alongside this user guide. As a local cache The primary use for Infinispan is to provide a fast in-memory cache of frequently accessed data. Suppose you have a slow data source database, web service, text file, etc: Using Infinispan is better than using a simple ConcurrentHashMap, since it has additional useful features such as expiration and eviction.
As a clustering building block for your applications If you need to make your application cluster-aware, integrate Infinispan and get access to features like topology change notifications, cluster communication and clustered execution. As a geographical backup for your data Infinispan supports replication between clusters, allowing you to backup your data across geographically remote sites.
While they share some methods and properties, be aware that there are semantic differences between them. The following chapters focus mostly on the embedded implementation. For details on the remote implementation refer to Hot Rod Java Client. CacheManagers are heavyweight objects, and we foresee no more than one CacheManager being used per JVM unless specific setups require more than one; but either way, this would be a minimal and finite number of instances.
The simplest way to create a CacheManager is: CacheManagers have a lifecycle and the default constructors also call start. Overloaded versions of the constructors are available, that do not start the CacheManager, although keep in mind that CacheManagers need to be started before they can be used to create Cache instances.
Once constructed, CacheManagers should be made available to any component that require to interact with it via some form of application-wide scope such as JNDI, a ServletContext or via some other mechanism such as an IoC container. When you are done with a CacheManager, you must stop it so that it can release its resources: If the CacheManager was clustered it will also leave the cluster gracefully.
Configuration Infinispan offers both declarative and programmatic configuration. Configuring caches declaratively Declarative configuration comes in a form of XML document that adheres to a provided Infinispan configuration XML schema.
Every aspect of Infinispan that can be configured declaratively can also be configured programmatically.
In fact, declarative configuration, behind the scenes, invokes the programmatic configuration API as the XML configuration file is being processed. One can even use a combination of these approaches.
For example, you can read static XML configuration files and at runtime programmatically tune that same configuration.
Or you can use a certain static configuration defined in XML as a starting point or template for defining additional configurations in runtime. There are two main configuration abstractions in Infinispan: Global configuration Global configuration defines global settings shared among all cache instances created by a single EmbeddedCacheManager.
Cache configuration Cache configuration is specific to the actual caching domain itself: You can specify as many named cache configurations as you need. One of these caches can be indicated as the default cache, which is the cache returned by the CacheManager.
Whenever they are specified, named caches inherit settings from the default cache while additional behavior can be specified or overridden. Infinispan also provides a very flexible inheritance mechanism, where you can define a hierarchy of configuration templates, allowing multiple caches to share the same settings, or overriding specific parameters as necessary.
Embedded and Server configuration use different schemas, but we strive to maintain them as compatible as possible so that you can easily migrate between the two. One of the major goals of Infinispan is to aim for zero configuration. A simple XML configuration file containing nothing more than a single infinispan element is enough to get you started.
The configuration file listed below provides sensible defaults and is perfectly valid. Non-basic configurations are very likely to use customized global and default cache elements.
Declarative configuration is the most common approach to configuring Infinispan cache instances.Oct 20, · Note: Today's entry is a technical article: it isn't funny.
