Vikas Saurabh commented on SLING-4216:
--------------------------------------
[~asanso], I just realized that serialization can get the last state safely but
we'd still need to take care of refreshing it with updates to repository while
the instance was down. As far I can see, serialized file isn't being used to
refresh filter yet -- but, I think this would need to be taken care of later.

> At the moment there isn't any limit to the number of MapEntry that are cached
> in memory.
> If the number of vanityPaths/alias is extremely high this can cause OOM.
> It would be good to have a way to limit the amount of memory used by the
> MapEntry cache.
