Florent Guillaume updated NXP-7274:
-----------------------------------
Impact type: [API added] (was: [ Configuration format change])
Upgrade notes:
In the <prefetch> element of a <doctype> you can now specify, in addition to a
schema or a property, any complex property like:
- book:author/pJob (complex property field)
- book:author/pName/FirstName (deep complex property field)
- attachments/0/name (field of a complex list)
- attachments/*/name (field of all elements of a complex list)
New API:
- DocumentModel.isPrefetched
was:TODO: new XML capability to configure complex properties to prefetch.
> Prefetch complex properties
> ---------------------------
>
> Key: NXP-7274
> URL: https://jira.nuxeo.com/browse/NXP-7274
> Project: Nuxeo Enterprise Platform
> Issue Type: Improvement
> Components: Core, Core SQL Storage
> Affects Versions: 5.4
> Reporter: Florent Guillaume
> Assignee: Florent Guillaume
> Priority: Major
> Fix For: 5.4.3
>
>
> There is a need to prefetch complex properties in addition to the simple
> properties that we can prefetch today.
> This will be useful for instance to fetch all the attached filenames in one
> batch instead of having them be lazy loaded.
> Impact:
> 1. core-schema: allow specification of which fields to prefetch,
> 2. VCS: actually understand this in terms of tables/columns, and do the
> prefetch of subnodes on node loading,
> 3. core: also do the prefetch at the core level into the
> DocumentModel/DocumentPart structures.
