Verified steps Write a rule with SELECT ... FROM 'topic/filter' WHERE ... using AWS IoT SQL Explicitly set the rule's SQL version (the current recommended version is 2016-03-23) Add a WHERE clause to filter which messages trigger the rule's actions; WHERE is evaluated before SELECT extraction Attach one or more actions (Lambda invoke, S3 put object, DynamoDB put/update item) to the rule Create an IAM role trusted by iot.amazonaws.com with permissions for each target action, and reference its roleArn on the action Configure a separate error action to capture action execution failures, since these are not captured automatically Known gotchas A false WHERE clause skips the rule entirely - there is no partial execution Each action needs its own IAM role/permissions; a single rule can have multiple actions with distinct roleArns Action failures are silent unless you configure an explicit error action on the rule
