The beauty of finished software
In a world where constant change is the norm, finished software —a software you can use forever with no unneeded change —provides a breath of fresh air. It’s a reminder that reliability, consistency, and user satisfaction can coexist in the realm of software development.

What the default routing guarantees is that the data will be uniformly distributed across the cluster which would reduce query hotspots when retrieving documents
