Hydrator: Run Configuration

User Stories:

• As a Hydrator user, I want to start, stop, and pause pipeline runs.
• As a Hydrator user, I want to know state and status of a pipeline run.
• As a Hydrator user, I want to configure arguments for a pipeline.
• As a Hydrator user, I want to view logs for a run.
• As a Hydrator user, I want to write preview data to a sink.
• As a Hydrator user, I want to specify how many records to preview.

Design:

• The Run Configuration player is comprised of the run/pause/stop button, configuration panel button, the status/state display, and the logs button.
• Display area will show Status, Start Time, Duration, and any state messages such as 'Starting schedule...' or 'Starting single run...'
• Clicking configuration panel button opens and closes the panel.
  • Arguments text boxes will be empty in default state.
• All buttons should have a Rest, Focused, and Pressed state.

• Data and Batch
  • The RUN button will change to pause only for Data and Batch pipelines, to "disable" a schedule.
  • 'Single Run' and 'Schedule' mode selector is available for Data and Batch pipelines.
  • Here, the configurations are for the selected mode. So,
    • if a single run is selected, and arguments are changed, the arguments apply to all single runs started from that point on, until they are changed again.
    • if schedule is selected, and arguments are changed, the arguments apply to the scheduled runs, started from that point on, until the arguments are changed.
    • if you go back to the Single Run mode after that, you see the arguments that were configured for Single Run earlier. Not the ones configured for schedule.

• Realtime
  • Run button will change to red "Stop" button when the pipeline is running.
  • Configuration panel will include arguments but not mode.

• Preview
  • Configuration panel will include 'Write to Sink' check box (default = unchecked) and 'Number of Records' text box (default = 5).
