 This connector can sync multiple DynamoDB tables at the same time and it does so without requiring explicit configuration for each one. On start and at regular time intervals (by default 60s) after, it queries AWS api for DynamoDB tables which match following criteria and starts Kafka Connect task for each of them:
 * ingestion TAG key set
-* stack(environment) TAG key and value set
+* environment TAG key and value set
 * DynamoDB streams enabled (in `new_image` or `new_and_old_image` mode)
