- Adds experimental support for reactor types in reactive CRUD and Sorting
repositories using RxJava1Template
- Refactor configuration and query classes to be reusable by reactive repositories
Original pull request: #130.
Removed the dynamic return type obtained from the ResultProcessor held in a query implementation field as this breaks thread safety. We now hand the type to read into the execution methods.
Adapted test cases accordingly and removed a bit of mocking.
Original pull request: #122.
Used the result processor projecting information to just fetch the selected fields and again to post process results to projection object/interfaces.
Added test for projection using DTO.

Defining <couchbase:env/> in XML configuration was causing a double
instantiation of DefaultCoreEnvironment, with subsequent warning in
logs:
[main] WARN c.c.client.core.env.CoreEnvironment - More than 1 Couchbase
Environments found (2), this can have severe impact on performance and
stability. Reuse environments!
This brings better performance when querying large views. Instead of
looping on a synchronously acquired list of documents to produce a list
of entities, the async API can be used internally to:
- query the view
- fetch the documents
- map each document to an entity
- collect into a List
One can then block on that Observable to get and return the List as
usual.
If the MappingCouchbaseConverter strict mode is enabled and no annotation is present, the property will not be eligible for document mapping.
This allows to specifically ignore some attributes in Couchbase only. For generally ignoring attributes in any Spring Data backing store, prefer the standard `@Transient`.
Closes#112
This change takes the `Version` annotated field into account when performing a `save` (either in the `CouchbaseTemplate` or transitively in a `CouchbaseRepository`).
Having such a field with a non-zero value means that a CAS is available, activating optimistic locking. Version 1.4 and below of Spring Data Couchbase was taking this CAS into account, whereas in 2.0 we switched to using `upsert` internally, which ignores the CAS.
This change brings the behavior of `save` (when there's a non-zero CAS) closer to what was observed in 1.4 versions: an `OptimisticLockingFailureException` can now be raised in case of CAS mismatch.
This commit adds support for auditing via the use of the four annotations (CreatedBy, LastModifiedBy, CreationDate, LastModificationDate), enabled via the EnableCouchbaseAuditing annotation.
As couchbase entities MUST have an id, the only case where the creation event can be detected is when the entity has a Version annotated field.
This commit allows to separate creation of beans dedicated to Spring Data Couchbase from the ones that can be made more common (SDK instances) and now can be provided externally through a a strategy interface, `CouchbaseConfigurer`.
Rather than having to extend a few methods from the base Configuration
class, `CouchbaseConfigurer` represents all the components that the Spring Data integration requires.
Configuration is based on Document annotation. When read of document takes place then touch action is executed on document. It is an asynchronous action so it does not block read. It is executed only on single reads (not view-based or N1QL-based ones).
