At this moment the dump processor seems to be sequential and uses only one of the 60 cores in our server.

This can be seen with htop

It would be nice to do some research about how we can parallelize the dump processing code. Some questions that I would like to answer:

  • Is it possible to parallelize the processing of gzip files? At this moment, the processor extends EntityTimerProcessor. Can that processor work in parallel? Could we use another approach for gzipped files?
  • Ideally, I would like to use cats.effect.IO or fs2, but I am not sure if this has been tried before or even if it is possible...

Another option discussed during the biohackathon would be to split the source dump in the same number of parts as CPUs, run the dockers in parallel in the different CPUs, and join the results. @nilshoffmann
