In my previous blog, i have mentioned how to integrate spring cache plugin in grails. In this blog we will see how we can use different attributes of cache.<\/p>\n

\n

Different attributes of cache :-<\/p>\n

    \n
  1. maxElementsInMemory- How many elements you can store in cache<\/li>\n
  2. overflowToDisk-The attribute overflowToDisk is true, meaning that whenever the maximum number of in-memory objects is reached, objects are swapped to disk<\/li>\n
  3. diskPersistent – if diskPersistent is false, it means when application server is restarted, in-memory cache is lost.<\/li>\n
  4. ttl(time to live seconds)- It denotes for how many seconds element will remain in cache?<\/li>\n
  5. memoryStoreEvictionPolicy – It is used to evict element from in-memory when the maximum number of in-memory objects is reached . Different type of eviction policy:<\/li>\n

    a) LRU (Least Recently Used): Oldest element will be evicted.
    \nb) LFU (Least Frequently Used): Element with least hits will be evicted.<\/ol>\n

    \n

    In grails, you can implement different cache attributes like this way.<\/p>\n

    [groovy]
    \nstudentCache(EhCacheFactoryBean) { bean ->
    \ncacheManager = ref("springcacheCacheManager")
    \ncacheName = "studentCache"
    \neternal = false
    \ndiskPersistent = false
    \nmemoryStoreEvictionPolicy = "LRU"
    \nttl = 3000
    \n}
    \n[\/groovy]<\/p>\n

    \n

    Hope this code will help you \ud83d\ude42<\/p>\n
