Why did we build it?
•
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
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
In this example we aggregate
the Tasks lists in all the sites in
http://kwizcom web
application
Select the type of lists that
this rule aggregates
Type the url of a list view
that will be used as the
query (aggregation)
definition
Define the
aggregation scope
kwizcom, 3
Step 3: Create aggregation caching rules
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 API
With 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)
Summary
 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!
