What does it do?<br />Aggregation Caching Job<br />App Server<br />Run cross-web application queries<br />Web apps.<br />Site collection<br />Site collection<br />Site collections<br />WFE Server<br />Store aggregated items in Farm-level cache<br />Aggregator web part<br />Cache<br />Web parts access the cache to quickly render cross-web site queries (instead of running these heavy queries in run-time)<br />
Why did we build it?<br /><ul><li>SharePoint provides an API only for site-collection scoped queries
Trying to aggregate items across site collections requires running queries in real time:
The solution includes:<br /><ul><li>Enterprise Aggregation Caching FeatureActivate this farm feature to enable aggregation caching in your farm.
Aggregation Caching Rules ListEach rule in this list defines a query, scope of aggregation, execution period and more.
CacheThe aggregation results are saved in the farm-level cache.
Aggregation caching JobThis job executes the aggregation caching rules according to their defined settings, and saves the results in the cache.</li></li></ul><li>Step 1: Activate the Enterprise Aggregation Caching Farm Feature<br />
Step 2: Configure the Aggregation Caching Rules list<br />In this page you create the Aggregation caching rules list.<br />
Step 3: Create aggregation caching rules<br />Go to the aggregation caching rules list<br />
Step 3: Create aggregation caching rules<br />Click to create a new aggregation caching rule<br />
In this example we aggregate the Tasks lists in all the sites in http://kwizcom web application<br />Select the type of lists that this rule aggregates<br />
Type the url of a list view that will be used as the query (aggregation) definition<br />Define the aggregation scope<br />
Step 3: Create aggregation caching rules<br />kwizcom, 3<br />Configure the user account used to run the aggregation<br />You can further define the exact time frame in which the aggregation should be executed<br />
Once a rule is saved it is processed by the aggregation caching job.<br />You can see when that rule was executed last time, and how long it took.<br />
Use KWizCom’s List Aggregator web part to connect to the Enterprise aggregation cache<br />Selecting an active caching rule connects the web part to that rule’s cached results<br />
In this example we display cached aggregation results from 17 site collections, response time is less than 2 seconds!!<br />
Cache public API<br />With the enterprise aggregation cache feature, your developers can:<br />Create cache rules programmatically<br />Request manual cache rule updateprogrammatically<br />Get a DataTable with the cache results<br />Simply poll the cache rule status for display (icon, description)<br />
Reduce aggregation load from your front-end servers.
Provide your users with much faster aggregation tool.
Now you can run cross web application queries!</li></li></ul><li>We value your feedback!<br />Does this solution answer your needs?<br />Need other/additional features?<br />Tell us what you think!<br />KWizCom continuously communicates with end users and customers, and according to your feedback we improve our solutions to help you get more productive with SharePoint.<br />Nimrod Geva<br />Product Group Manager, KWizCom<br />firstname.lastname@example.org<br />22<br />
