Hi Manik, The purpose is the usual that the application would want to take some action on expiry of the entry. Ofcourse the application can also start a timer in parallel but those timers may again need to be synced up in case of distributed apps. However, your explanation brings out another question - is there an additional overhead (memory related) using expiry on the cache entries as compared to keeping an active control over the cache entry creation and deletion. An application using only cache entries with expiry. Thanks, Kapil only tested for whether they are expired in one of several ways: removed. again be removed. expired. It will again be removed. time the entry expired, but rather at the time Infinispan realises the entry has expired (which may be later). _________________
