public final class GigaspacesCache
extends AbstractDistributedCache

Gigaspaces implementation of Castor JDO Cache.

Gigaspaces supports a wide variety of cache topologies, allowing the user to distribute and/or replicate application data as needed. This cache instance replicates this flexibility by allowing you to configure it (and thus the underlying Gigaspaces instance) as follows.

 <cache-type type="gigaspaces">
    <cacheUrl>/./</cacheURL>
    <cacheProperties>schema=cache</cacheProperties>
 </cache-type>
 
As mentioned briefly above, the main issue is the cache topology usage. Per definition, Gigaspaces caches can be started in various modes:


Each of the above can run in replicated or partitioned mode. This means you should run several instance in one of the above mode using the relevant schema name, total_membres and id.

instance 1:
"/./myCache?schema=cache&cluster_schema=replicated&total_members=2&id=1"

instance 2:
"/./myCache?schema=cache&cluster_schema=replicated&total_members=2&id=2"


or

instance 1:
"/./myCache?schema=cache&cluster_schema=partitioned&total_members=2&id=1"

instance 2:
"/./myCache?schema=cache&cluster_schema=partitioned&total_members=2&id=2"


When running the cache in server or in embedded mode, you must have the cache schema to be used, i.e. 'schema=cache'.

public GigaspacesCache()
Method Detail

initialize

public void initialize(java.util.Properties params)
                throws CacheAcquireException
Lyfe-cycle method to allow custom initialization of cache implementations.

Specified by:
initialize in interface Cache
Overrides:
initialize in class AbstractBaseCache
Parameters:
params - Parameters to initialize the cache (e.g. name, capacity).
Throws:
CacheAcquireException - If cache can not be initialized.

initialize

public void initialize(java.lang.String implementation,
                       java.util.Properties params)
                throws CacheAcquireException
Normally called to initialize CoherenceCache. To be able to test the method without having com.tangosol.net.CacheFactory implementation, it can also be called with a test implementations classname.

Parameters:
implementation - Cache implementation classname to initialize.
params - Parameters to initialize the cache (e.g. name, capacity).
Throws:
CacheAcquireException - If cache can not be initialized.

getType

public java.lang.String getType()
Indicates the type of this cache.

Returns:
The cache type.
