---------------------------------
Summary: Performance problem with roles many members
Key: FC-307
URL: https://issues.apache.org/jira/browse/FC-307
Project: FORTRESS
Issue Type: Improvement
Affects Versions: 2.0.7
Reporter: Shawn McKinney
Assignee: Shawn McKinney
Fix For: 2.0.8
This issue brings performance improvements to situations where the
role.occupants is enabled on role entries. The problem, is groups with many
members can be costly to update and even read. Insertions are slow because
large groups are expensive in LDAP. There are mitigating factors on the server
side that are beyond the scope of this discussion.
Reads are slow, because pulling entries back with 1000's even hundreds of
thousand members is actually pulling a bunch of data across. So, what we can
do, is only pull back the members when absolutely necessary.
This issue addresses this by adding a method to the RoleP and RoleDAO classes
called readConstraints. It only pulls back the constraints and parents on the
entry.
This method replaces the role validation, constraint and hierarchical
processing that occurs in the AdminMgrImpl class.
