Technical Debt: Cyclic dependency between LoadBalanceStats and ServerStats #465

Open jbpextra opened 4 years ago

jbpextra commented 4 years ago

There exists a cyclic dependency between classes LoadBalancerStats and ServerStats that has caused in the past up to 12% productvity loss.

We at Skuld.ai have developed a tool that can find cycles that are especially negative for the development health status. It is widely backed by research that the existence of cyclic dependencies has the potential to create ripple effects during development in an exponential way. We have found this cyclic dependency has a detrimental effect mounting to an approximate 4.5% productivity loss. This figure is based on changed made in the past, which experienced a negative impact in varying degree with a record high of a 12% productivity loss in @elandau’s 8d9d700b584feeaf6a64ba39a0265a256a090f66

@elandau Can you (or anyone else for that matter) confirm that this cyclic dependency has been problematic for you in the past?
