(Glue-2105) Q: How can I perform an initial full load of mass data with several jobs in parallel?

It's possible by creating multiple variants. Please follow these steps:

  1. Create an extractor with full load delta type.
  2. Create multiple variants with different selections. All variants combined must cover all data. For example, if we do selections on a field containing a year, we need to have a variant for each year.
  3. Run extraction for all created variants.

If you want to use some delta mechanism for extraction after a full load, please follow these steps:

  1. Add global setting to allow delta value reset. This can be done in transaction /DVD/RL_TM. Choose table /DVD/GL_CUS_VALS and add setting ALLOW_DELTA_VALUE_RESET.
  2. Create another extractor with desired delta type (same source and a target as the first full load extractor).

  3. Go to delta tools manage tab.
  4. Edit delta value to last value which was extracted. For example, if we did a full load using variants with selections on a field containing a year, we need to set the last year in selection as the value of delta.
  5. Perform delta run only from the manage tab. Do not execute variant directly because full load would be done again as it would be the first execution of extractor.
