pom.xml
- updated CouchbaseMock dependency to the official release on maven central, which now includes the required commit.
CouchbaseTemplate.java
- remove creation of CouchbasePersistentEntityIndexCreator
- there can only be a single CouchbaseMappingContext and CouchbasePersistentEntityIndexCreator, not sure why there was code dealing with multiples of each, and there was no corresponding tests for these assumptions.
- no longer does the job of a @Configuation class by gluing beans together with their dependencies.
CouchbaseMappingContext.java
- removed references to auto index creation, that functionality should be a completely separate concern.
CouchbasePersistentEntityIndexCreator.java
- as well as implementing ApplicationListener, it now also implements InitializingBean
- when afterPropertiesSet() is called it uses CouchbaseMappingContext#getPersistentEntities to retrieve the list of entity candidates for index creation. This will handle the creation of indices for entities known at @Configuration time.
- for entities not in the initialEntitySet of the MappingContext, the ApplicationListener will handle those entities at runtime.
- this is needed because the AbstractMappingContext will emit events when it is initialized via InitializingBean, and any beans that depend on MappingContext and also implement ApplicationListener expecting to receive those events won't.
- in our case because Spring will have fully initialised the CouchbaseMappingContext instance before passing it to the CouchbasePersistentEntityIndexCreator instance we won't get those events.
- added a boolean flag to indicate if automatic index creation is to be enabled or now, passed in by the factory method that creates this bean.
- minor logging cleanup, use property placeholders where appropriate
AbstractCouchbaseConfiguration.java
- added a new factory method for the CouchbasePersistentEntityIndexCreator bean.
- CouchbaseMappingContext no longer has anything to do with index creation, other than supplying a candidate list of entities that may need indices.

Support for projection is only for properties of the top-level entity. For instance, in UserSubmission, only the properties below can be specified in the projection. Projection support does not provide means of specifying something like address.street - you can only project (or not project) the whole address property. However, the address type in your resultType could have a subset of the properties in Address.
If the corresponding submissions in the resultType contained only the userId property
public class UserSubmission extends ComparableEntity {
private String id;
private String username;
private List<String> roles;
private Address address;
private List<Submission> submissions;
Support for Distinct - I have appropriated the MongoDB model for Distinct. It defines a separate DistinctOperationSupport class (within ExecutableFindByQuerySupport) which supports the distinct( distinctFields ) api and execution. The DistinctOperationSupport class has only a distinctFields member, and a 'delegate' member, which is an ExecutableFindByQuerySupport object. TBH, I don't see the advantage over simply adding a distinctFields member to ExecutableFindByQuerySupport
Amend #1 - changes as discussed in Pull Request
- clean up test entity types
Amend #2
- Eliminate DistinctOperationSupport class. In MongoDB, only distinct on a single field is supported, so the returnType from distinct was very different from the returnType of other query operations (all(), one() etc. (but so is count(), and it doesn't need it's own class)). In Couchbase, distinct on any fields in the entity is allowed - so the returned type could be the domainType or resultType. And as(resultType) still allows any resultType to be specified. This makes it unnecessary to have combinations of interfaces such as DistinctWithProjection and DistinctWithQuery.
- Clean up the interfaces in ExecutableFindByQuery. There are two types of interfaces (a) the TerminatingFindByQuery which has the one(), oneValue() first(), firstValue(), all(), count(), exists() and stream(); and (b) the option interfaces (FindByQueryWithConsistency etc), which are essentially with-er interfaces. The changes are:
1) make all the with-er interfaces base interfaces instead of chaining them together. (I don't know why there isn't simply one interface with all the with-er methods).
2) make the ExecutableFindByQuery interface extend the Terminating interface and all the with-er interfaces.
Amend #3
- Add execution support for collections
Amend #4
- Add tests for collections. This includes a new CollectionAwareIntegrationTests class which extends a new JavaIntegratationTests class which extends the existing ClusterAwareIntegrationTests.
- Fixed up several issues collections issues that were uncovered by the tests.
- Did further cleanup of OperationSupport interfaces.
Amend #5
- Revert changes to interfaces in *Operation
- Sorted interfaces in same order for consistency (because of the chaining of interfaces, fluent methods must be called in order).
