paStash Commands

This WIP outlines the nature of paStash commands and their general usage.

What?

Commands are pluggable pipeline functions users can inject in their logic using npm modules. Example:

  .filter('method', 'INVITE')
  .groupBy('response')
  .divide('timestamp',1000,data)
  .data(data)

Usage

In order to understand the potential usage we'll create a simple pipeline applying multiple cascading actions to an array of objects.

input {
  stdin{}
}

filter {
  json_fields {}
  command {
    debug => false
    cmd => ".divide('age',2,data).multiply('eyes',2,data).data(data)"
    plugins => ['@pastash/command_chain','@pastash/command_math']
  }
}

output {
  stdout {}
}
