Events

When a query uses a statement which makes a change to ThingsDB, then internally ThingsDB will create an event to apply these changes. Events are applied in order on each node; so database consistency is guaranteed.

A single query might contain several statements and make many changes. All changes within a query will be grouped in a single event.

In the documentation we try to make clear if a function will generate an event or not. If you only want to read information from ThingsDB, you should try to avoid functions which generate an event. Functions on a list or set do not create an event when called on a variable.
