Antonio Sanso commented on SLING-4216:
--------------------------------------
the reason why I was hesitating to add bloom filter in the past was really to
avoid situations like this.
And I did actually did not change my mind :S. At the end of the day IMHO if a
situation like you said will happen (possible but unlikely) it is better to
rebuild the bloomFilter file from scratch
> Limit the number of vanityPath MapEntry

> 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.
