Trying to filter out rows, where a certain column has NULL values
I have a dataset of almost 2 billion rows. I need to filter out rows, where a certain column has NULL values.
What is the best and fastest way to do it?
I tried creating a DataFlow using the mySQL option, but the flow has been running for more than 24 hours now.
Could any of you please help in understanding how this process can be made to run faster?
