Modify Nuxeo Query Maker
-------------------------
Key: NXP-3911
URL: http://jira.nuxeo.org/browse/NXP-3911
Project: Nuxeo Enterprise Platform
Issue Type: Improvement
Components: Core SQL Storage, Search / Query
Affects Versions: 5.2 GA
Reporter: Thierry Martins
Assignee: Thierry Martins
Fix For: 5.2.1
Nuxeo suffers of huge performance problem while the repository is growing up :
the navigation becomes more and more difficult and the problem origin is how we
are using NX_ALLOWED_ACCESS stored procedure : this and function is called on
each line of hierarchy table and the query planner of the database never build
subqueries, even if we set a huge cost to this stored procedure.
So we have to manually build a sub- select for the user query and on this
result run NX_ALLOWED_ACCESS.
