created_at represents the time when the configuration has been persisted to disk.
loaded_at represents the time when the configuration has actually been used.
If created_at is larger than loaded_at, then the Core needs a reload in order
to apply the latest configuration.
if created_at is lower than laoded_at, then the Core applied the latest
configuration.
The value of updated_at is irrelevant and shouldn't be used.
For the API endpoint /v3/process two new query parameter are introduced
in order to list only processes that match a pattern for the id and the
reference: idpattern and refpattern. The pattern is a glob pattern. If
patterns for both are given, the results will be intersected. If you use
other query parameters such as id or reference, they will be applied
after the result of the pattern matching.
If a value for a placeholder needs escaping, add the character to
escape with an "^" to the name of the placeholder, e.g. {memfs^:}.
This will escape all occurences of ":" in the value for {memfs}
with a "\".
If PUT /process/:id is called in order to replace an existing
process config with an invalid process config, the existing
process was deleted and an 409 was returned. A subsequent GET on
the previous process would then return a 404, which is not
what you expect. The previous process needs to stay in place.
