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:
- Embedded - cache running as part of the application VM (/./myCache?schema=cache)
- Remote - means you need to run cache server and have relevant url at the client to connect to it (jini//*/*/myCache)
- Master local - means you need to run a cache server and have relevant url at the client to connect to it. The URL should include 'useLocalCache' as part of it (jini//*/*/myCache?useLocalCache)
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'.

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 interfaceCache
- Overrides:
initialize
in classAbstractBaseCache
- 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 havingcom.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.
