JobApp

etlflow.JobApp
trait JobApp extends ZIOAppDefault with ApplicationLogger

This is the entry point for a EtlFlow Job application (See below sample).

import etlflow._
import etlflow.task._
import zio._

object MyJobApp extends JobApp {

 def executeTask(): Unit = logger.info(s"Hello EtlFlow Task")

 val task1: GenericTask[Unit] = GenericTask(
     name = "Task_1",
     function = executeTask()
 )

 def job(args: Chunk[String]): RIO[audit.Audit, Unit] = task1.execute
}

Abstract methods

def job(args: Chunk[String]): RIO[Audit, Unit]

Concrete methods

final def execute(cliArgs: Chunk[String]): RIO[Audit, Unit]

This is the core function which runs the job with auditing (start and end).

This is the core function which runs the job with auditing (start and end).

It also converts command-line arguments passed to application into json key value pair. For e.g. if you run application with args "arg0 arg1 arg2 arg3" it will parse and convert these args to "{"0":"arg0", "1":"arg1", "2":"arg2", "3":"arg3"}"

final override def run: ZIO[ZIOAppArgs, Any, Any]

This is just a wrapper around default run method available with ZIOAppDefault to call execute(Chunk[String])
