- Package size
  - number of rows selected for each package of package based source
- Package size MB
  - input for number of MB, with compute button Calculate
Selection filter - section is generated based on the selection in the specific (Glue-1911) Fetcher
Additional Fetcher config - section generated for editable parameters of the (Glue-1911) Fetcher
- Load type
  - a dropdown of all available Load type
- Use cursor
  - enabled, data from the source will be processed by the packages
Additional Consumer config - section generated for editable parameters of the (Glue-1911) Consumer
