# Inspecting Cached Data

With Toggle Automatic Inspect on Selection enabled, if you click a feature type or transformer with a cache, it will automatically be displayed in Visual Preview (covered in the next section):

Specific data caches (for example a single output port on a transformer) can be inspected by clicking on the feature cache icon:

Inspecting data this way can allow you to quickly debug and develop workspaces, but keep in mind that if you are inspecting a large number of features or features with complex geometry, the caching required for automatic inspection might introduce performance challenges.

**TIP**

*Be aware that caching data causes the translation to be slower, and to use system resources such as disk space.*

*Data caching is very useful while developing a workspace but should be turned off before putting a workspace into production.*
