-------------------------------------------------------------------------
I am just letting people know that I am about to merge this (1) (17220) where
config will look like this (2)
There will be grouped / nested startup_checks section. The (not so obvious)
advantage of what we did there is that if you want to introduce a new startup
check, you do not need to change anything configuration-related. We are parsing
the config into the map where key type of that map is an enum so in order to
include a new check, one has to just add a new entry into that enum type and
you are done. No change on configuration side about that in cassandra.yml.

> Move cassandra.yaml toward a nested structure around major database concepts

> Key: CASSANDRA-17292
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17292
> Project: Cassandra
> Issue Type: Improvement

> Reporter: Caleb Rackliffe
> Assignee: Caleb Rackliffe
> Priority: Normal
> Fix For: 5.x

> Recent mailing list conversation (see "[DISCUSS] Nested YAML configs for new
> features") has made it clear we will gravitate toward appropriately nested
> structures for new parameters in {{cassandra.yaml}}, but from the scattered
> conversation across a few Guardrails tickets (see CASSANDRA-17212 and
> CASSANDRA-17148) and CASSANDRA-15234, there is also a general desire to
> eventually extend this to the rest of {{cassandra.yaml}}. The benefits of
> this change include those we gain by doing it for new features (single point
> of interest for feature documentation, typed configuration objects, logical
> grouping for additional parameters added over time, discoverability, etc.),
> but one a larger scale.
> This may overlap with ongoing work, including the Guardrails epic. Ideally,
> even a rough cut of a design here would allow that to move forward in a
> timely and coherent manner (with less long-term refactoring pain).
