 Notifications are retried a configurable number of times using an exponential backoff algorithm. It is safe for multiple instances of the framework to poll for notifications concurrently.
 
 ### Hook
-A *Hook* is an event the framework will emit to whenenver a projection is added, dropped or updated via a change set. Your application can handle these events how it chooses, e.g. by making an HTTP request, or publishing a message to an SNS topic. Unlike node events, the handlers are asynchronous. It is advised not to share hooks between handlers since if one handler fails but another succeeds the built in retry mechanism will re-notify both handlers.

 ## Data Definition
 All of above objects (Projections, Entities, Data Frames, etc) are defined using a domain specific language, which is dynamically converted into SQL and applied using a database migration tool called [Marv](https://www.npmjs.com/package/marv). Whenever you need to make an update, simply create a new JSON or YAML migration file in the configurable migrations folder. A JSON schema is available in /lib/schema.json
