 title: Observer Concepts
 ---
 
-Fluo supports complex processing by running user provided code in Observers. Observers are triggered
-by notifications. An Observer requests that the system run it when a certain column is modified. When
-another transaction modifies an observed column, it will persist a notification that later causes
-the Observer to run.  When an Observer is run, its provided with the row and column that caused it
-to run along with a transaction. Fluo worker processes running across a cluster will execute
-Observers.
+Fluo supports incremental processing with Observers and Notifications.  Notifications are persitent
 
 Review comment:
   should be `persistent`
