Appharborアプリケーションにリンクされている完全に空のRavenHQデータベースがあります。データベースが現在使用しているスペースの量は、私のブロンズアカウントで使用可能な25MBのうち1.1MBです。以前、データベースにはレコードが含まれていましたが、ManagementStudioの「コレクションの削除」を使用してレコードを削除しました。

初めてsession.Store（myobject）を呼び出すとき、および.SaveChanges（）を呼び出す前に、次のエラーが発生します。

System.InvalidOperationException: Url: "/docs/Raven/Hilo/AccItems"

Raven.Database.Exceptions.OperationVetoedException: PUT vetoed by Raven.Bundles.Quotas.Triggers.DatabaseSizeQoutaForDocumetsPutTrigger because: Database size is 45,347 KB, which is over the allowed quota of 25,600 KB. No more documents are allowed in.

さて、ドキュメントは確かにそれほど大きくないので、このエラーが何を意味するのかわかりません。特に、SaveChangesを呼び出してセッションを閉じていないので、その時点でデータベースにアクセスしたことはないと思います。 （）。何か案は？これがコード自体です。

    XDocument doc = XDocument.Parse(rawXml);
    var accItems = ExtractItemsFromFeed(doc);
    using (IDocumentSession session = _store.OpenSession())
    {
        var dbItems = session.Query<AccItem>().ToList();
        foreach (var item in accItems)
        {
            var existingRecord = dbItems.SingleOrDefault(x => x.Source == x.SourceId == cottage.SourceId);
            if (existingRecord == null)
            {
                session.Store(item);
                _logger.Info("Saved new item {0}.", item.ShortName);
            }
            else
            {
                existingRecord.ShortName = item.ShortName;
                _logger.Info("Updated item {0}.", item.ShortName);
            }
            session.SaveChanges();
        }
    }

Any other comments about the style of this code would be most welcome, as I was unsure of the best way to approach the "update existing item or create if it isn't there" scenario.

The answer here was as follows.

RavenHQ support found that the database was indeed oversized, but it seemed that the size reported in the Appharbor-branded RavenHQ control panel was incorrect. I had filled up the database way over the limit with a previous faulty version of the code posted above, so the error message I received was actually correct.

Fixing this problem without paying to upgrade the database wasn't straightforward, as it's not possible to shrink the database. As I also wasn't able to delete my single Appharbor/RavenHQ database or create another one that left me with the choice of creating an entirely new Appharbor application, or registering directly with RavenHQ for a new account. I chose the latter. The RavenHQ-branded control panel is slightly different to the Appharbor one, in that it has the ability to create and delete databases.

So to summarize: there doesn't seem to be any benefit to using RavenHQ as an add-on to Appharbor - you might as well go and get a proper free RavenHQ account.
