Add JSON schema to collection creation using reactive API. Refactor MongoJsonSchema to interface with default implementations for JsonSchemaObject and Document-based schemas. Make fields final and methods static where possible.
Add minItems/maxItems/additionalItems properties to ArrayJsonSchemaProperty. Add missing overrides to NullJsonSchemaProperty.
Slightly rename methods for item/property counts. Add generics, Javadoc, minor tweaks.

We now can create a $jsonSchema that can be used as a validator when creating collections and as predicate for queries. Required fields and properties get mapped according to the @Field annotation on domain objects.
MongoJsonSchema schema = MongoJsonSchema.builder().required("firstname", "lastname")
.properties(string("firstname").possibleValues("luke", "han"),
object("address").properties(string("postCode").minLength(4).maxLength(5)))
.build();
resulting in the following schema:
{
"type": "object",
"required": [ "firstname", "lastname" ],
"properties": {
"firstname": {
"type": "string", "enum": [ "luke", "han" ],
},
"address": {
"type": "object",
"properties": {
"postCode": { "type": "string", "minLength": 4, "maxLength": 5 }
}
}
}
}
Query usage:
MongoJsonSchema schema = MongoJsonSchema.builder()
.required("address")
.property(object("address").properties(string("street").matching("^Apple.*"))).build();
List<Person> person = template.find(query(matchingDocumentStructure(schema)), Person.class));
Collection validation:
MongoJsonSchema schema = MongoJsonSchema.builder().required("firstname", "lastname")
.properties(string("firstname").possibleValues("luke", "han"),
object("address").properties(string("postCode").minLength(4).maxLength(5)))
.build();
template.createCollection(Person.class, CollectionOptions.empty()
.schema(schema)
.failOnValidationError());

Convert spaces to tabs. Reorder methods. Add tests, nullability annotations, author tags and slightly rearrange documentation. Migrate tests to AssertJ. Extend year range in license headers.

Refactor MongoConverter.mapValueToTargetType to imperative method instead of returning a function for easier consumption. Adapt return types in Javadoc to the actual return type. Remove undocumented type parameters. Add overload using reified entity and return type generics. Slight documentation tweaks.

Add rename and add methods to MongoOperations.
Map query, and use execute method to run errors through the execption translator. Add Javadoc and missing issue references.
Move to assertJ.
Also add fluent and reactive api counterpart and fix BsonValue to plain java Object / domain Type conversion.
Provide Kotlin extensions for operations added.

We now support distinct queries via MongoTemplate to select distinct field values based on a collection and query.
List<String> distinctNames = template.findDistinct("name", Person.class, String.class);
List<String> distinctNames = template.query(Person.class).distinct("name").as(String.class).all();

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.

In BasicMongoPersistentEntity.verify() we now properly call the super method to make sure the comparators that honor the @Field's order value are initialized properly.
Use native field names for NamedMongoScript query instead of relying on metadata-based mapping as NamedMongoScript is considered a simple top-level type. Migrate tests to AssertJ.

Introduce Aggregation.toPipeline(…) method to render the aggregation pipeline directly. Adapt code using aggregation pipelines. Consider allowDiskUse and batchSize cursor options. Move introduction versions to 2.1. Mention migration to cursor-based aggregation in reference docs.
Original pull request: #515.
We now use the driver native option for aggregate instead of a plain command execution. This is necessary as of MongoDB 3.6 the cursor option is required for aggregations changing the return and execution model.
Still we maintain the raw values of AggregationResult as we used to do before. However, relying on executeCommand to change aggregation behavior in custom code will no longer work.
Tested against MongoDB: 3.6.RC3, 3.4.9 and 3.2.6
Along the the way we opened up Aggregation itself to expose the AggregationOptions in use und deprecated the $pushAll option on Update since it has been removed in MongoDB 3.6.

We now provide and register a Binary to byte[] converter to provide conversion of binary data to a byte array. MongoDB deserializes binary data using the document API to its Binary type. With this converter, we reinstantiated the previous capability to use byte arrays for binary data within domain types.
