README

cmd

Contains applications (apps) used in Substation deployments. Apps are organized by either the infrastructure they are deployed to (e.g., AWS) or the source of the data (e.g., file, http).

Any app that implements the ingest, transform, load (ITL) functionality of Substation is named substation and shares the same configuration file format (see build/config/ for more information).

app.go

Contains the core Substation application code. This code can be used to create new Substation applications.

aws/lambda

Contains apps deployed as AWS Lambda functions.

development/

Contains apps that aid in testing and development.

Functions

func New

func New() *substation

New returns an initialized Substation app. If an error occurs during initialization, then this function will panic.

Concurrency is controlled using the SUBSTATION_CONCURRENCY environment variable and defaults to the number of CPUs on the host. In native Substation applications, this value determines the number of transform goroutines; if set to 1, then multi-core processing is not enabled.
