As I understand your scenario is not primary use case for JBossCache. People from Hibernate brought up this issue some time ago and as the result the method putForExternalRead was added: /** | * Under special operating behavior, associates the value with the specified key for a node identified by the Fqn passed in. | * <ul> | * <li> Only goes through if the node specified does not exist; no-op otherwise.</i> | * <li> Force asynchronous mode for replication to prevent any blocking.</li> | * <li> invalidation does not take place. </li> | * <li> 0ms lock timeout to prevent any blocking here either. If the lock is not acquired, this method is a no-op, and swallows the timeout exception.</li> | * <li> Ongoing transactions are suspended before this call, so failures here will not affect any ongoing transactions.</li> | * <li> Errors and exceptions are 'silent' - logged at a much lower level than normal, and this method does not throw exceptions</li> | * </ul> | * This method is for caching data that has an external representation in storage, where, concurrent modification and | * transactions are not a consideration, and failure to put the data in the cache should be treated as a 'suboptimal outcome' | * rather than a 'failing outcome'. | * <p/> | * An example of when this method is useful is when data is read from, for example, a legacy datastore, and is cached before | * returning the data to the caller. Subsequent calls would prefer to get the data from the cache and if the data doesn't exist | * in the cache, fetch again from the legacy datastore. | * <p/> | * See <a href="http://jira.jboss.com/jira/browse/JBCACHE-848">JBCACHE... for details around this feature. | * <p/> | * | * @param fqn <b><i>absolute</i></b> {@link Fqn} to the {@link Node} to be accessed. | * @param key key with which the specified value is to be associated. | * @param value value to be associated with the specified key. | * @throws IllegalStateException if {@link #getCacheStatus()} would not return {@link org.jboss.cache.CacheStatus#STARTED}. | */ | void putForExternalRead(Fqn fqn, K key, V value); | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4268556#...
