How you define constants

Contributors

You can create and use constants to define a value, which can be used across a single workflow. Constants are defined at a workflow level.

The constants used in the workflow and their value are displayed in the monitoring window of the workflow during planning and execution. You must use unique names for constants.

You can use the following naming conventions to define constants:

  • Uppercase for the first letter of each word, without underscores or spaces between words

    All terms and abbreviations should use upper case—​for example, ActualVolumeSizeInMB.

  • Uppercase for all letters

    You can use underscores to separate words—​for example, AGGREGATE_USED_SPACE_THRESHOLD.

You can include the following as values for workflow constants:

  • Numbers

  • Strings

  • MVEL expressions

    Expressions are evaluated during the planning and execution phases of the workflows. In the expressions, you must not reference variables that are defined in a loop.

  • User inputs

  • Variables
