Substation applications that assist with development.

Benchmark

Use this application to benchmark the performance of Substation configurations by sending a configurable number of events through the system and reporting the total time taken, the number and rate of events sent, and the
amount and rate of data sent.

Options

Flags	Type	Description	Required
file	string	Location of a file containing data to transform.	Yes
concurrency	integer	Number of concurrent data transformation functions to run. Defaults to the number of CPUs available.	No
config	string	Location of a file containing a Substation configuration. Defaults to an empty configuration.	No
count	integer	Number of events to process. Defaults to 100,000.	No
cpu	boolean	Enable CPU profiling. Defaults to false (no profiling).	No
mem	boolean	Enable memory profiling. Defaults to false (no profiling).	No

Example Usage

substation-bench -config /path/to/config.json -file /path/to/data.dat

Kinesis Tap

Tap into and transform data from an AWS Kinesis Data Stream in real-time.

Options

Flags	Type	Description	Required
stream-name	string	Name of the Kinesis Data Stream to fetch records from.	Yes
stream-offset	string	Determines the offset of the stream. Must be either "earliest" or "latest". Defaults to earliest.	No
config	string	Location of a file containing a Substation configuration. Defaults to the configuration file in the local directory (./config.json)	No

Example Usage
