Hi,

I'm having a performance issue each time a file is saved. Saving a file triggers a "write new descriptions" job which takes a very long time. When tracing through "writeNewResourceDescriptions", a lot of things happen, in particular *all* files in the project are parsed completely, new resource descriptions are computed and then links are resolved.

The question is: is there a way to optimize this job? For instance, is there enable some sort of incremental resource description update?

I'm using XText 2.3

Thanks in advance!
Lionel

You could limit the number of objects exposed to the index. By default every object that has a name attribute will be exported. Think if this is always desirable.

Thanks for the suggestion. I have already changed the default to export only some of the objects, but the scope is still global. Maybe by also limiting the scope, only the files imported the changed objects will be updated?

Thanks again!
Lionel
