Review Comment:
@jacek-lewandowski @smiklosovic
I have prototyped a configuration approach you suggested and it looks good
at first glance. So, we could have multiple configuration sources under the
same interface:
- `Config` class;
- `CassandraRelevantProperties`
- `CassandraRelevantEnv`
Having at the same time a read-only access layer represented with
`ConfigurationRegistry` + `ConfgurtionValue<T>`, we will be able to turn the
following source code:
```
if (conf.auto_snapshot_ttl != null)
{
try
{
holder.autoSnapshoTtl = new
DurationSpec.IntSecondsBound(conf.auto_snapshot_ttl);
}
catch (IllegalArgumentException e)
{
throw new ConfigurationException("Invalid value of
auto_snapshot_ttl: " + conf.auto_snapshot_ttl, false);
}
}
```
into
```
registry.getValue(String.class, "auto_snapshot_ttl")
.map(DurationSpec.IntSecondsBound::new,
(e, v) -> new ConfigurationException("Invalid value of
auto_snapshot_ttl: " + v, false))
.ifPresent(v -> holder.autoSnapshoTtl = v);
```
It looks much better and suits our needs. Here is the prototype of the
`ConfigurationValue<T>` class:
https://github.com/apache/cassandra/compare/trunk...Mmuzaf:cassandra:cassandra-15254-apply#diff-16d8aa644f29a8e76deedbb8dd760530530c90d4dd14ad4c4ea60823b84ea79dR31
I guess we could implement that in another issue (cassandra-15254?), so here
we just need to decide what to do with the CRP default values.
WDYT?
