> Based on our experiments, we noticed that at the end of each hop, fit
> multiple would start using a lot of memory (from 80 GB to ~ 140 GB on
> the master host of our gcp cluster) and we attributed that memory spike
> to the final function.
> Removing the final function brought down the memory to around 30-40 GB
> and also made the places10 query 3 times faster
