filters look the same

Parameters restricts the data at the source

Filters returns all of the data and filters in place

Parameters and filters affected by caching and snapshot settings

CachingCaching is not enable by default

Can be used to improve the performance of retrieving reports by storing a copy in the ReportServerTempDB

Configured to set an expiry time for the cache

Consider “pre heating” the oven using data driven subscriptions

Execution process for cached instances1. Retrieves most up-to-date data and processes

report2. Creates intermediate report and stores

intermediate result in the cache in ReportServerTempDB

3. Flags intermediate report as a cached instance 4. Renders report from cached instance5. Later requests for the same report are retrieved

from the cached copy

SnapshotsSnapshot are created in advance of the user

browsing

Stored in the ReportServerDB and are persistent

Can be used to create historical data

• Execution process for snapshots

Creation of snapshot is scheduled for a specific point in time

Requests are satisfied by retrieving and rendering the snapshot

The intermediate report is created and the result is stored as a snapshot in the report server database
