DNS
DNS processes values by querying domains or IP addresses in the Domain Name System (DNS).
By default, this processor can take up to 1 second per DNS query and may have significant impact on end-to-end data processing latency. If Substation is running in AWS Lambda with Kinesis, then this latency can be mitigated by increasing the parallelization factor of the Lambda.
Interpretation Methods
The processor supports these interpretation methods:
- object
- data
