![]() Once you do that, you need to enable the ‘ is cluster’ check-box. If you want distributed caching, enable Redis in cluster mode. Multiple ColdFusion nodes can point to same Redis server. ADOBE COLDFUSION ENTERPRISE 2018 INSTALLOnce you install it, you need to add the server details in the caching page. Similar to Memcached, Redis also needs to be installed separately. If you want distributed caching, you can install multiple Memcached servers and then add comma separated IP addresses of Memcached servers in this section. So if one of the Memcached server goes down, others will take the load and keep on serving. Multiple ColdFusion nodes can point to same Memcached server. Here you can specify the IP address and port of the Memcached server you have just installed. A new section has been added to the caching page – Memcached cache settings. Once you install Memcached, integrating it with ColdFusion is pretty simple. While ehcache and JCS come bundled with ColdFusion, Memcached and Redis need to be installed separately. You can have two applications, both using Memcached, one with timeToLive value as 60 seconds and another with the value 120 seconds. Either you can specify the path of property file that will contain key-value pairs of these settings or you can directly specify them in the form of a struct In application.cfc file, you can specify the settings for the caching engine specific to this application. If no caching engine is provided at application.cfc level, it will pick the default server cache engine. So, you can have multiple applications, each using different caching engine which itself would be different from the default caching engine specified at the server level. It will print the name of the caching engine which you would have specified in application.cfc. ADOBE COLDFUSION ENTERPRISE 2018 CODEWe can run the same code present inside some application. Here you can specify the name of the caching engine which needs to be used for the given application. We have introduced a new property which can accept one of the four values – ehcache, jcs, redis, memcached. Users can specify different cache engine at application level in application.cfc. If eternal is true, elements will not expire ever. Max elements is the default value for max number of elements which can be stored in the cache.Max life is the default value for the max life span of any element in cache in seconds.Max idle is the default value for max idle time for any element in cache in seconds.You can specify server level cache settings for each caching engine from admin in caching page or directly change at lib/rediscache. So this is how simple it is to switch caching engine at the server level. Now let’s go to CF admin and switch the caching engine.Ĭlick on JCS and submit and rerun the downloaded code snippet. It inserts an element into the cache, retrieves it, and prints the current caching engine being used.Ĭachegetengineproperties is a newly added function which will return the caching engine currently being used by the page. Let’s try running this simple caching code, cacheEngines. As a result, Redis can’t effectively harness multiple cores. Slower than same VM in-memory caching solutions like ehcache, JCS.Supports many datatypes – Strings, Hashes, Lists, Sets, etc.Cache memory can reside on different systems.Distributed caching and cache replication is easier.There is no support for idle time, regions, and statistics (we have written a wrapper).The size of a key cannot be greater than 250 bytes.Memcached is slower than same VM in-memory caching solutions like ehcache and JCS.memcached consumes fewer memory resources for metadata.Memcached can easily handle websites with high traffic.For simple key-value pairs, Memcached is more memory efficient than Redis.Memcached server is multi-threaded. As a result, it can effectively harness multiple cores.Cache memory can reside on a different system.Support for database backup (not related to cfquery).In the 2018 release of ColdFusion, we have added support for 3 new caching engines So we need to integrate more caching engines. Depending upon your application, one caching engine might suit your application more than another. There are many caching engines available in the market and each has its pros and cons. ColdFusion already has support for caching using ehcache. ![]()
