Which step is the Meta Loader responsible for in the data extraction process?

  • Parallelizing the data extraction
  • Processing the extracted data
  • Extraction of information schema (correct)
  • Overloading the source system

    • What is the main characteristic of the data extraction process performed by the Meta Loader?

  • Effortless
  • Low data volume
  • Parallelized
  • Extremely fast (correct)

    • Why is parallelizing the Meta Loader not worth the effort?

  • It slows down the extraction process
  • It requires additional resources
  • It increases data volume
  • It overloads the source system (correct)
