Andres de la Peña commented on CASSANDRA-17212:
-----------------------------------------------
I agree that we should move toward nesting, the part that I'm not convinced
about is grouping warn/fail thresholds.
That dev mail discussion thread about nesting was started during the guardrails
prototype, that's why guardrails are already nested. We might change how
properties are grouped and/or named in the future, but I also think that those
changes can be easily retrofitted at a later stage, and that shouldn't stop us
from adding new guardrails with the current structure. The guardrails framework
systematizes how certain soft/hard limits are treated, so it should make it
easier for us to move to a different yaml structure once we have agreed on it,
compared to porting many ad-hoc limits.
