Dani Rey commented on OAK-3595:
-------------------------------
[~chetanm] I think this should be reopened and fixed for the following reasons.
I think the behavior is neither fail fast nor consistent.
If it would be fail fast, it would fail during creation of the index
definition. Of course this is not possible, because indexes get created via
repository operation, not via a specialized GUI which might produce errors.
Therefore the fail is delayed to the next startup. This is unexpected and
problematic. Servers either get restarted very rarely (during migrations) or
automatically (offline segmentstore revision cleanup). In both cases a failing
startup is a nightmare.
I consider the behavior inconsistent, because the misconfiguration is savely
ignored during creation, but prevents repository to register upon restart.
Savely ignoring it during restart would be consistent.
To assert index definition quality I suggest to create an according
SlingHealthCheck.
