Performance issues when accessing Reads in Interval/Feature based walkers. #1246

Open vruano opened 8 years ago

vruano commented 8 years ago

I currently have a feature driven walker in gatk-protected that is slower than a read-walker equivalent due to the repetitive Read iterator re-instantiation when accessing overlapping reads using the ReadContext.

Ideally the engine (FeatureManager?) would try to reuse open read iterators instead of creating them for each feature/interval.

We will definitely do this for beta!

Since this was specifically requested by @vruano, we should attempt it for alpha-1.
