Overview

Note:

When passing ConditionExpression as input to an Aws::Client method, you can use a vanilla Hash:

{
  condition: "Condition", # required
  value: "ConditionValue",
  target_column: "TargetColumn", # required
}

Represents an individual condition that evaluates to true or false.

Conditions are used with recipe actions: The action is only performed for column values where the condition evaluates to true.

If a recipe requires more than one condition, then the recipe must specify multiple ConditionExpression elements. Each condition is applied to the rows in a dataset first, before the recipe action is performed.
