Arguments represent constant values that are passed as a Collection to the Handlers. To acces Arguments in the Handlers, the handler has to request a ConfiguredArgumentsCollection as a parameter.


Filters are provided in different flavours.

  • DataFilters
  • Formatters

To access Filters in the Handlers, the handler has to request a IEventDataConverter as a parameter.


DataFilters create a new EventData container and convert the properties to the desired destination.

Pointer Syntax Description
-> property -> destination mapps property to destination property in the new table
  property maps property to the new table


Formatters can be used to format the EventData to a string output in the given format.

The syntax for formatting uses the following format:

  • ${PROP}

The Formatter ${Date:yyyy-MM-ddTHH:mm:ss.sssZ} takes in a DateTime from the Date property and formats it to a ISO 8601 date string format

Pointer Syntax Description
<- property <- ${propertyA}_${propertyB} Creates a string value formatted with the value of propertyA and propertyB with a _ between
Predefined Formatters

There are some predefined Formatters that take a configuration and produce a string in a certain format.

Key Pointer Syntax Description
json <- json <- [property, property2 -> destination2] Creates a json containing property and destination2
