Performance issues with CouchDbRepositorySupport.getAll()

[max-vogler]

I'm using Ektorp with an out-of-the-box Cloudant database (in case you don't know what Cloudant is, it is an extension of CouchDB).

I get terrible performance when calling CouchDbRepositorySupport.getAll() to retrieve all documents from a collection (15s for 60 documents). Debugging showed, that designDocContainsAllView() returns false and Ektorp uses a single query for every document.

    public List<T> getAll() {
        if (designDocContainsAllView()) { // <-- false!
            return queryView("all");
        }
        return loadAllByAllDocIds();
    }

Without any problem, I can replace the getAll() call with

repo.getDb().queryView(new ViewQuery().allDocs().includeDocs(true), MyPojo.class);

So there is a working view (_all_docs) to query all documents, why isn't it used instead of the horribly slow loadAllByAllDocIds()? And what is the difference between the all view and _all_docs view?
