-### MongoDB 4.0 Transactions
-
-As of version 4 MongoDB supports [Transactions](https://www.mongodb.com/transactions). Transactions are built on top of
- `ClientSessions` and therefore require an active session.
-
-`MongoTransactionManager` is the gateway to the well known Spring transaction support. It allows applications to use 
-[managed transaction features of Spring](http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html).
-The `MongoTransactionManager` binds a `ClientSession` to the thread. `MongoTemplate` automatically detects those and operates on them accordingly.
-
-```java
-@Configuration
-static class Config extends AbstractMongoConfiguration {
-
-	@Bean
-	MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
-		return new MongoTransactionManager(dbFactory);
-	}
-
-	// ...
-}
-
-@Component
-public class StateService {
-
-	@Transactional
-	void someBusinessFunction(Step step) {
-
-		template.insert(step);
-
-		process(step);
-
-		template.update(Step.class).apply(Update.set("state", // ...
-	};

-== Running CI tasks locally
-
-Since Concourse is built on top of Docker, it's easy to:
-
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your `test.sh` script before sending it out.
-* Experiment against a new image before submitting your pull request.
-
-All of these use cases are great reasons to essentially run what Concourse does on your local machine.
-
-IMPORTANT: To do this you must have Docker installed on your machine.
-
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-8-jdk-with-mongodb /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-Next, run the `test.sh` script from inside the container:
-+
-2. `PROFILE=none spring-data-mongodb-github/ci/test.sh`
-
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
-
-If you need to test the `build.sh` script, do this:
-
-1. `mkdir /tmp/spring-data-mongodb-artifactory`
-2. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github --mount type=bind,source="/tmp/spring-data-mongodb-artifactory",target=/spring-data-mongodb-artifactory springci/spring-data-8-jdk-with-mongodb /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github` and the temporary
-artifactory output directory at `spring-data-mongodb-artifactory`.
-+
-Next, run the `build.sh` script from inside the container:
-+
-3. `spring-data-mongodb-github/ci/build.sh`
-
-IMPORTANT: `build.sh` doesn't actually push to Artifactory so don't worry about accidentally deploying anything.
-It just deploys to a local folder. That way, the `artifactory-resource` later in the pipeline can pick up these artifacts
-and deliver them to artifactory.
-
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

- * {@link ExecutableMapReduceOperation} allows creation and execution of MongoDB mapReduce operations in a fluent API

- * back the results from the {@link org.bson.Document}. However, it is possible to define an different

- * The collection to operate on is by default derived from the initial {@literal domainType} and can be defined there
- * via {@link org.springframework.data.mongodb.core.mapping.Document}. Using {@code inCollection} allows to override the
- * collection name for the execution.
