Hi,

i have implemented a first version of sharding support. I added a new annotation "QueryFields" to change the core query routine for a document.

The next step is to update the reference mappings to include the query fields in the reference object. But first I want some feedback from you.

Issue: #304

Regards
Thomas

Looks interesting. So the queryFields will be stored in the reference document? What else do you see as being needed to support sharding fully?

Yes we need to add the query fields to the reference document to make a correct shard query and after this we support sharding fully so we need nothing more.

I'll plan to take a look at this tomorrow on my local machine with a small sharding setup. @tecbot: Please let me know if anything is still TODO.

@jmikola, @jwage : I pushed the initial DBref logic for sharding also I implemented lazy loading for referenece one inverse side. Currently shard keys for embedded or reference documents are not supported.

@tecbot: I can't find contact info for you, but could we sync up in IRC or Google chat later today to discuss the PR? I'm in the #doctrine-dev channel.

  • rename QueryFields to ShardedFields
  • throw exceptions if user want to change sharded fields
  • add the possibility to set sharded fields for embedded and reference documents
  • code cleanup and more unit testing

if you want you can help :), i haven't started any task of this at the moment.

Why is $ref missing here? I can understand removing $db, as it's optional, but reference objects require $ref and $id.

What is the $sort parameter used for, if this is for creating a proxy object?
