-----------------------------------
Summary: 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: security
Affects Versions: 1.5.12
Reporter: Alex COLLIGNON
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.
