Data Resource - Content Resource

About

A content resource is a data resource that:

• contains data known as static data resource (for instance, a sql table or a file)
• or returns data known as runtime data resource (for instance, a SQL Query)

Type

Static

A static data resource is a data resource where the content is stored on disk in a connection that can be selected with a data selector.

The following data operations have impact on the content of stored data resources:

• drop - drop the resource (delete the resource content included)
• truncate - delete the content via metadata update, not the resource
• upsert - upsert data into the content
• insert - insert data into the content
• update - update the content
• delete - delete parts or all of the content

Runtime

A runtime data resource returns its content at runtime (ie the data is not stored but computed). In tabulify, a runtime data resource is known as a runtime.

Diff

Difference in content can been seen via:

• the diff operation
• the digest attributes such as MD5.
