This section explains each of the properties in the configuration blade.
This associates the Agent to a specific Collection (default to that of the current Data Stream).
Attributes to Substitute
The columns or attributes of the input payload to monitor for missing values.
The options to substitute the selected numeric (int, double, decimal, etc.) attributes are:
Substitute With (Non Number types)
The selected non-numeric attributes are always substituted with the previous value.
The number of previous records to include to calculate the minimum, maximum, or average aggregation.
Consider empty strings as null
Tick to evaluate empty strings as a missing value, or pass them unchanged.
Trim row when there are null values at start
Tick to remove the whole row from the output if there are null values on the first row - since it cannot be substituted.
Before configuring the Transformation, please ensure that its input endpoint is connected to a parent Agent which will be sending data to it.
This endpoint is used to receive data from the parent Agent.
Events received from the parent Agent are made available to this endpoint, but null values in the attributes to be substituted are replaced as configured.
Errors encountered during the execution of this Agent will be published on this endpoint.
