> Speed up ACE node name generation
> ---------------------------------
>
> Key: OAK-5025
> URL: https://issues.apache.org/jira/browse/OAK-5025
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.5.12
> Reporter: Alex COLLIGNON
> Assignee: angela
> Priority: Minor
>
> Currently,
> {{o.a.j.oak.security.authorization.accesscontrol.Util#generateAceName}} is
> traversing all the existing ACE of a certain node in order to generate
> continuous numbering (allow0, allow1, allow2).
> While that certainly helps to produce human readable names, it represents
> quite a performance bottleneck when the number of existing ACE starts to grow.
> Since the naming is a pure implementation detail, my proposal is to keep the
> continuous numbering for the first hundreds of nodes and then use a random
> number to generate unique names in a faster fashion.
