Components Common

ETL jobs are defined in evs files and consist of components connected by flows.

In this chapter, all components are described.

There are two kinds of component commands:

  • Component’, i.e. component name begins with capital letter – these are intended to be used in evs file (EVL job structure files),
  • evl component’, i.e. command ‘evl’ with the first argument to be a name of the component – these invocations are to be used as standalone commands, which can be run from commandline.
