To optimze the extraction process even before the data extraction process begins, ensure that only necessary data is being extracted and the extraction job is structured in the most efficient order/way. Have business or other knowledgeable party to check the output for reasonableness or compare total size/rows/items from the source to the sink. This final check will ensure completeness and accuracy of the data extracted. If the data extracted is not accurate and doesn't contain all items, it also affects reliability, availability and timeliness.

Let's say you're working with a massive database, pulling data for your company's quarterly reports. Instead of running one giant query every time, you could break it down into more manageable chunks. Maybe split it by department or region. That way, you're not overloading the system all at once, and you can pinpoint any issues more easily. Another trick is to schedule your extractions during off-peak hours. If you're pulling data from a system that gets hammered during business hours, running your queries at night or on weekends can reduce the risk of interruptions. And don't forget, if you're pulling the same data over and over again, consider storing it locally instead of hitting the source every time. It'll save time and resources.
