I need some explanation of the structure of the Node interface. Below are some excerpt from documentation A Node is a named logical grouping of data in the JBoss Cache. A node should be used to contain data for a single data record, for example information about a particular person or account. // creates with default settings and starts the cache | | Cache cache = DefaultCacheFactory.getInstance().createCache(); | Fqn personRecords = Fqn.fromString("/org/mycompany/personRecords"); | | | Node rootNode = cache.getRoot(); | Node personRecordsNode = rootNode.addChild(personRecords); | | // now add some person records. Fqn peterGriffin = Fqn.fromString("/peterGriffin"); | | // the addChild() API uses relative Fqns | Node peter = personRecordsNode.addChild(peterGriffin); | | peter.put("name", "Peter Griffin"); | peter.put("ageGroup", "MidLifeCrisis"); peter.put("homicidal", Boolean.FALSE); | Correct me if I have misunderstood it [1] According to above two a node should contain data related to one record of database [2] If 1 is correct then each node should store data in from of colName, colValue pair Is above scheme recommended one or I can use it other way around ? e.g. [A] I am storing a record in individual nodes as a object against PK of that record and not in colName, colValue fashion. so my cache contains one node per record and each node's map contains only one value which is the record VO (value object). I think I am wasting the maps associated with nodes by doing this. What is your opinion? [B] If I store set of records at node rather than one record (not correct according to API docs), so my cache contains one node per table. I think this way I am utilizing the node's map.
