Global Cache: Replace some Caches with Artifacts

1 Initial Problem

When GlobalCache was introduced, it was analyzed which contents from the database do not have to be reloaded with every request, but only with certain actions (e.g. reloading language). Since then, these database contents can be loaded into the GlobalCache, making it available more quickly and reducing the load on the database.

Currently these are data from the domains:

• Language
• Object Definition
• Control Flow
• Components
• Template (HTML)
• Template (Blocks)
• Template (Variables)
• Events
• Global Screen

Besides the fact that some caching mechanisms are no longer supported, the introduction of Artifacts has also created a new possibility to store such data (even faster available).

2 Conceptual Summary

For each of the above-mentioned areas it should be checked whether the data should not be stored in an Artifact. It must be taken into account that certain artifacts will then have to be created not only through the setup process, but also, for example, in administration.
At least the following areas can be migrated according to the current state of knowledge:

• Object Definition
• Components
• Events

Note: As part of the refactoring of ilCtrl with ILIAs 8, the ilCtrl information has already been relocated to an artifact.

3.2 User Interface Details

3.3 New User Interface Concepts

none

4 Technical Information

These modifications can be considered as refactoring and the feature request is to be understood as information.

5 Privacy Information

No new user related data will be processed or collected with this refactoring.

6 Security Implications

It is ensured that artifacts are only created when building ILIAS (resp. the classmap). Artifacts are PHP arrays that cannot be read out via the web server in the browser.
