Pipeline Expressions and Functions

This page was generated from content adapted from the AWS Developer Guide

Expressions

• Note You can create pipelines that have dependencies, such as tasks in your pipeline that depend on the work of other systems or tasks. If your pipeline requires certain resources, add those dependencies to the pipeline using preconditions that you associate with data nodes and tasks. This makes your pipelines easier to debug and more resilient. Additionally, keep your dependencies within a single pipeline when possible, because cross-pipeline troubleshooting is difficult.

• Note The fields preceded by the AT (@) sign indicate those fields are runtime fields.

Date and Time Functions

• Note The date/time format for AWS Data Pipeline is Joda Time, which is a replacement for the Java date and time classes. For more information, see Joda Time - Class DateTimeFormat.
