@aali.khalid is taking to the TestBash New Zealand stage to talk to us about big data pipelines 
What data pipelines look like, how we can test them and how do we automate them.
If you’ve got questions for Ali about the talk, add them here 
Remember to 
questions that you like to show appreciation for others and help @jamesespie see what questions are popular to ask live.
For a lot of the Quality checks you discussed. Are these things typically run in a test environment or more in production?
What are the most common bugs with data pipelines? Is there a particular section that is more fragile than the others?
In your experience @aali.khalid, does the business model get defined clearly for you to perform your tests? If not, how do you tackle on-the-fly scenarios?
