I just started using Hail2.0 and find it a bit of a struggle to perform QC.
The main issue I face is the extremely long time it takes to do a count() or count_cols().
In Hail1.0 I would use sample_num and it would be much faster than the count methods.
Is there any similar method in Hail2.0? Did anyone find good solutions or tips for dealing with this issue?
