Processor: Subtract

One number is created on output for each number with the same properties in both inputs. For each input item the processor leaves only significant keys, drops the others and puts the result. If there is no common set of properties between both inputs, the output is the empty set.

Parameter Description
Input Types Table (number)
Output Types Table (number)
Significant Keys (significant_keys) List of keys to map items from the inputs for applying the specified operation. It is typically used by processors that take multiple inputs and perform operations on them. When inputs have the same sets of keys it does not need to be specified. When inputs have different sets of keys, it must be specified and it must allow only 1:1 items mapping from the given inputs, otherwise the probe will go into error state.
Enable Streaming (enable_streaming) Makes samples of output stages streamed if enabled. An optional boolean that defaults to False. If set to True, all output stages of this processor are streamed in the generic protobuf schema.
