AND/OR logic

You can use operations that include AND/OR logic to match message attributes or message body properties.

AND logic

You can apply AND logic using multiple property names.

Consider the following policy:

{
  "customer_interests": ["rugby"],
  "price_usd": [{"numeric": [">", 100]}]
}

It matches any message attribute or message body property with the value of customer_interests set to rugby and the value of price_usd set to a number larger than 100.

Note

You can't apply AND logic to values of the same attribute.

OR logic

You can apply OR logic by assigning multiple values to a property name.

Consider the following policy:

{
   "customer_interests": ["rugby", "football", "baseball"]
}

It matches any message attribute or message body property with the value of customer_interests set to rugby, football, or baseball.

Note

Currently, you can't use SNS filters to apply OR logic across different message attributes. Instead, you can use multiple SNS subscriptions with different endpoints to achieve the same effect. For example, assume that you have message attributes named customer_interests and customer_preferences. To apply OR logic across both attributes, create an SNS subscription to match each message attribute. Then, you can use your subscriber application to consume both types of messages through the different endpoints.
