"How to use JBoss Cache" To view the discussion, visit: http://community.jboss.org/message/547973#547973 -------------------------------------------------------------- Hi I'm new to Jboss Cache and I have few very basic questions. In our system we would like store information about tokens (used for authentcation of request) in Cache. Simply first external request will create token after uthentcaton in cache and next requests will be validated against token (we wll check if given token exists in cache). First question is, should we create one node e.g. /tokens and put all tokens (key=token string, value=some accoutn info) to this node? I've found in documentation that +"One purpose of grouping cache data into separate nodes is to minimize transaction locking interference, and increase concurrency. So for example, when multiple threads or possibly distributed caches are acccessing different accounts simultaneously."+ Should we create our tokens between different nodes to reduce problem with concurrency? How many nodes we should create? We expect that we wll have about few thousend of token in cache in peak hours. Second questions is if we get object from cache (using get() method) can we change values of object not related to key? Do we get copy of object or reference. in documentation is information: +The data access methods are similar to the collections http://java.sun.com/j2se/1.5.0/docs/api/java/util/Map.html?is-external=true Map interface, but some are read-only or return copies of the underlying the data'+ but I could not found what 'some' methods, there is no info about 'get' method.
