Session.Query + BulkInsert losing metadata

[Bruno]

Hello group,

I am doing a session.query/bulk insert to update records on my db and the operation runs ok except that I'm losing all my metadata after the records are updated.

The code is simple and looks like:

     // loads a list of recs...

     var docs = sess.Query<T>()

                            .Take(batchSize)

                            .Skip(count)

                            .ToList();

     // do stuf....

     // bulk update

using (var bulkInsert = store.BulkInsert(options: new BulkInsertOptions {

OverwriteExisting = true, 

SkipOverwriteIfUnchanged = true

}))

{

docs.ForEach(d => bulkInsert.Store(d));

}

Notes: 

• I cannot use the patch functionality b/c I need to run complex back-end code on each record;
  
• Client/Server in use is 3.0.30037
  

Is this the default behavior?

What do I need to do in order to be able to preserve my metadata after a bulk update since the GetMetadataFor can only be used per document?

Thanks.

Yes, you are overwriting the data, it you want to preserve the metadata, you need:

docs.ForEach(d => bulkInsert.Store(d, sess.Advanced.GetMetadataFor(d), d.Id));

Gmail code, the order of the params may be different.

Thanks for the reply, Oren!

And for the record, we need to use the method RavenJObject.FromObject(d); to convert from an entity to RavenJObject.
