Switched to ClassUtils.isAssignableValue(…) in getPotentiallyConvertedSimpleRead(…) as it transparently handles primitives and their wrapper types so that we can avoid the superfluous invocation of the converter infrastructure.
We previously used MongoTemplate.insertAll(…) which determines the collection to insert the individual elements based on the type, which - in cases of entity inheritance - will use dedicated collections for sub-types of the aggregate root. Subsequent lookups of the entities will then fail, as those are executed against the collection the aggregate root is mapped to.
We now rather use ….insert(Collection, String) handing the collection of the aggregate root explicitly.
Extend copyright license years. Slightly reword documentation. Use IntStream and insertAll to create test fixture.

We now use _id lookup for remove operations that query with limit or skip parameters. This allows more fine grained control over documents removed.

We now use AbstractMongodbQuery.fetch() instead of AbstractMongodbQuery.fetchResults() to execute MongoDB queries. fetchResults() executes a find(…) and a count(…) query. Retrieving the record count is an expensive operation in MongoDB and the count is not always required. For regular find(…) method, the count is ignored, for paging the count(…) is only required in certain result/request scenarios.

We now return the first result when executing findFirst/findTop queries. This fixes a glitch introduced in the Kay release throwing IncorrectResultSizeDataAccessException for single entity executions returning more than one result, which is explicitly not the desired behavior in this case.

We now avoid calling ….inCollection(…) with a fixed, one-time calculated collection name to make sure we dynamically resolve the collections. That's necessary to make sure SpEL expressions in @Document are evaluated for every query execution.
Move method from AggregationCommandPreparer and AggregationResultPostProcessor to BatchAggregationLoader. Extract field names to constants. Tiny renames to variables. Add unit test for aggregation response without cursor use. Migrate test to AssertJ.

We now send aggregation commands along a cursor batch size for compatibility with MongoDB 3.6 that no longer supports aggregations without cursor. We consume the whole cursor before returning and converting results and omit the 16MB aggregation result limit. For MongoDB versions not supporting aggregation cursors we return results directly.

We now make sure that we convert empty sources to the corresponding target type. This prevents entity instantiation from failing due to incorrect argument types when invoking the constructor.
