Can your users query 100 lists, located in 50 site

collections, each with over 5000 items,

and display the results in less than 3 seconds?

A Cross-web application aggregation caching service, enabling end-users to run

extensive queries at fast response with minimum load on your SharePoint WFE

servers.

cache to quickly render cross-web app. queries

• SharePoint provides an API only for site-collection scoped queries

• Trying to aggregate items across site collections requires running

queries in real time:

• Slow response time

• Heavy load on the front-end servers

• Performance degrades when amount of data/sites increases

Why did we build it?

Companies with multi-site collection deployments need a

better way to aggregate and display information!

How does this work?

The solution includes:• Enterprise Aggregation Caching Feature

Activate this farm feature to enable aggregation caching in your

farm.

• Aggregation Caching Rules List

Each rule in this list defines a query, scope of aggregation, execution

period and more.

• Cache

The aggregation results are saved in the farm-level cache.

• Aggregation caching Job

This job executes the aggregation caching rules according to their

defined settings, and saves the results in the cache.

Step 1: Activate the Enterprise Aggregation Caching Farm Feature

Step 2: Configure the Aggregation Caching Rules list

In this page you create the Aggregation caching rules list.

Step 3: Create aggregation caching rules

Go to the aggregation caching rules list

Step 3: Create aggregation caching rules

Click to create a new aggregation caching rule

Select the type of lists that this rule aggregates

In this example we aggregate the Tasks lists in all the sites in

http://kwizcom web application

Type the url of a list view that will be used as the

query (aggregation) definition

Define the aggregation scope

Step 3: Create aggregation caching ruleskwizcom, 3

Configure the user account used to run the aggregation

You can further define the exact time frame in which the

aggregation should be executed

Once a rule is saved it is processed by the aggregation caching job.

You can see when that rule was executed last time, and how long it

took.

OK...so now what?

Use KWizCom’s List Aggregator web part to connect to the

Enterprise aggregation cache

Selecting an active caching rule connects the web part to that

rule’s cached results

In this example we display cached aggregation results from 17 site collections,

response time is less than 2 seconds!!

Cache public APIWith the enterprise aggregation cache feature, your developers can: Create cache rules programmatically Request manual cache rule update programmatically Get a DataTable with the cache results Simply poll the cache rule status for display (icon,

description)

Centrally-managed, Enterprise

aggregation caching mechanism.

Reduce aggregation load from your front-

end servers.

Provide your users with much faster

aggregation tool.

Now you can run cross web application

queries!
