Being immutable and row oriented are two main requirements for making things possible. - -=== Modules - -So far we have identified the following modules: - -* Schema: Should read a set of given classes and create a schema (Metagraph) from it -* Mapping: Should take care of hydrating from results to domain objects and dehydrating vice versa. It can depend on schema, but only as a provider for property matching -* Lifecycle: Lifecycle must not depend directly on mapping, but should only care whether an Object and its Relations are managed or not -* Querying: Generates cypher queries, depends on schema - -Those will be reassembled as packages inside Spring Data Neo4j. -There are no short-term planes to create additional artifacts from those. - -[[schema]] -==== Schema - -We used the new Spring Data JDBC project as blueprint for some ideas now. -Spring Data JDBC doesn't build up the schema upfront. -Each time, a persistent entity is requested from the mapping context, that entity is read and fully described, including properties and all associations. -We can implement it in the same way. -The mapping context would return instances of `Neo4jPersistentEntity` which implements a Spring Data interface. -To fulfill the contract however, we would read the classes and store them in a schema that is free of Spring dependencies. -That way we we can avoid a compile time dependency to Spring Data and have an independent schema module, in which the mapping context is the connecting adapter. - -Spring Data JDBC doesn't restrict the supported or scanned classes from Spring Data sides. -Our schema should also support non-annotated classes and be smart about naming things, but we will require at least the `@Node` or `@Relationship` annotation to the outside world. - -The schema will life independent from Spring classes in `org.springframework.data.neo4j.core.schema`. -Each property of a class that is not identified as a simple type by `org.springframework.data.neo4j.core.schema.Neo4jSimpleTypes` will be considered describing a relationship and thus required to be part of the schema as well. - -==== Context - -NOTE: Context in this sections refers especially to dirty tracking and dealing with state of entities. - -We decided against a context for tracking changes, much like Spring Data JDBC did. - -=== Other principles - -* Ensure that the underlying store (Neo4j) leaks as little as possible into the mapping. - I.e. reuse `@Id` etc. and avoid adding custom variants of annotation whenever possible. - -=== The embedded "problem" - -Supporting the embedded use case will be solved on the drivers level. - -=== Relationships - -=== Simple relationships - -We provide `@Relationship` for mapping relationships without properties. -This annotation shall be used for 1:1 and 1:n mappings. -It provides an attribute to specifiy the name of the relationship. - -[source,java] ----- -@Node("User") -static class UserNode { - - @Relationship(type = "OWNS") - List bikes; -} - -static class BikeNode { - - UserNode owner; - - UserNode renter; -} ----- - -=== "Rich" relationships - -There should be no means of using a relationship as aggregate root in SDN (like it is today the case with `@RelationshipEntity`). -Instead we suggest that properties of relationships are mapped to POJOs. -This has the following requirements: -On the node representing the start node, the relationship (either 1:1 or 1:n) has to be annotated with `@Relationship` specifying the type of the end node like this: - -[source,java] ----- -@Relationship("HAS_MEMBER", endNodeType = SoloArtistEntity.class) -private List member = new ArrayList<>(); ----- - -The POJO, in this case `Member` is required to have the following structure : - -[source,java] ----- -public static class Member { - - private SoloArtistEntity artist; - - private Year joinedIn; - - private Year leftIn; -} ----- - -It must have exactly _one_ attribute of `endNodeType`. -All other attributes are mapped from the properties of the relationship. - -The motivation behind this is that a relationship needs to be manifested in the domain model, -but as the domain model usually isn't a graph, it manifests itself as a thing, not a relationship as is. -We prefer that people use the mapping framework domain centric, not database centric. -In the relational world it is an anti pattern to map out n:m (intersection) tables. -If they have attributes, a schema is usually refactored into a 1:n and a n:1 table and an entity structure. -We don't need another entity, though. - -[[labels]] -=== Labels - -NOTE: Do we need support for dynamic labels?

Auto-Configuration Classes + +#### `FalkorDBAutoConfiguration.java` +- **Purpose**: Main auto-configuration class that creates core beans +- **Beans Configured**: + - `Driver` - FalkorDB Java driver (using `DriverImpl`) + - `FalkorDBClient` - Database client (using `DefaultFalkorDBClient`) + - `FalkorDBMappingContext` - Mapping metadata (using `DefaultFalkorDBMappingContext`) + - `FalkorDBTemplate` - Main template for database operations +- **Key Features**: + - Parses URI from properties (supports `falkordb://` and `redis://` schemes) + - Validates required `database` property + - All beans use `@ConditionalOnMissingBean` for customization + +#### `FalkorDBRepositoriesAutoConfiguration.java` +- **Purpose**: Auto-configures repository support +- **Features**: + - Conditional on `FalkorDBTemplate` bean + - Imports `FalkorDBRepositoriesRegistrar` for repository scanning + - Can be disabled with properties + +#### `FalkorDBHealthContributorAutoConfiguration.java` +- **Purpose**: Provides health indicator for Spring Boot Actuator +- **Features**: + - Only activates when Actuator is on classpath + - Conditional on `FalkorDBTemplate` bean + - Registers `FalkorDBHealthIndicator` + +### 2. Configuration Properties + +#### `FalkorDBProperties.java` +- **Properties**: + - `spring.data.falkordb.uri` - Connection URI (default: `falkordb://localhost:6379`) + - `spring.data.falkordb.database` - Graph/database name (required) +- **Features**: + - Annotated with `@ConfigurationProperties` + - Generates metadata for IDE support + +### 3. Health Indicator + +#### `FalkorDBHealthIndicator.java` +- **Purpose**: Reports FalkorDB connection health +- **Implementation**: + - Extends `AbstractHealthIndicator` + - Executes simple query to test connectivity + - Reports database name and version in details + +### 4. Repository Support + +#### `FalkorDBRepositoriesRegistrar.java` +- **Purpose**: Registers repository beans dynamically +- **Features**: + - Extends `AbstractRepositoryConfigurationSourceSupport` + - Scans for `@EnableFalkorDBRepositories` annotation + - Integrates with Spring Data Commons infrastructure + +### 5. Build Configuration + +#### `pom.xml` +- **Key Dependencies**: + - `spring-data-falkordb` (core module) + - `spring-boot-autoconfigure` + - `spring-boot-actuator-autoconfigure` (optional) + - `jfalkordb` (FalkorDB Java driver) +- **Plugins**: + - `spring-boot-configuration-processor` for metadata generation + - Maven Compiler Plugin with Java 17 target + +### 6. Resource Files + +#### `META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports` +- Registers auto-configuration classes for Spring Boot 3.x +- Lists: + - `FalkorDBAutoConfiguration` + - `FalkorDBRepositoriesAutoConfiguration` + - `FalkorDBHealthContributorAutoConfiguration` + +## Key Design Decisions + +### 1. Driver Instantiation +- Uses `new DriverImpl(host, port)` directly +- Matches the pattern from integration tests +- Simpler than using factory methods + +### 2. Entity Converter Construction +- Uses 3-parameter constructor: `(mappingContext, entityInstantiators, client)` +- Client parameter needed for relationship loading +- Matches the pattern from `FalkorDBTwitterIntegrationTests` + +### 3. Template Construction +- Uses 3-parameter constructor: `(client, mappingContext, converter)` +- All three parameters are required +- Provides full control over mapping and conversion + +### 4. Property Naming +- Uses `spring.data.falkordb.*` prefix +- Consistent with Spring Data conventions +- Simple URI-based configuration + +### 5. Spring Boot 3.x Compatibility +- Uses `AutoConfiguration.imports` file (not `spring.factories`) +- Compatible with Spring Boot 3.x and Spring Data 4.0.0-RC1 +- Follows modern Spring Boot starter patterns + +## Usage Example + +### 1. Add Dependency + +```xml + + com.falkordb + spring-boot-starter-data-falkordb + 1.0.0-SNAPSHOT + +``` + +### 2.

persisted through Cypher and the dedicated `setNodeVectorProperty` function that Spring Data Neo4j uses to persist the property. - -NOTE: Spring Data Neo4j only allows one `Vector` property to be present in an entity definition. - -NOTE: Please be aware that a persisted `float` value differs from a read back value due to the nature of floating numbers. - -[[custom.conversions]] -== Custom

converters you need to take care of converting your type to *and* from a Neo4j Java Driver `Value`. -If your converter is supposed to work only with custom query methods in the repositories, it is

`Neo4jPersistentPropertyConverter` via the `converter` attribute -and an optional `Neo4jPersistentPropertyConverterFactory` to construct the former. -With an implementation of `Neo4jPersistentPropertyConverter` all specific conversions for a given type can be addressed. -In addition, `@ConvertWith` also provides `converterRef` for referencing any Spring bean in the application context implementing -`Neo4jPersistentPropertyConverter`.

-Having skipped more than one major upgrade:: -While Neo4j-OGM can be used stand-alone, Spring Data Neo4j cannot. -It depends to large extend on the Spring Data and therefore, on the Spring Framework itself, which eventually affects large parts of your application. -Depending on how the application has been structured, that is, how much the any of the framework part leaked into your business code, the more you have to adapt your application. -It gets worse when you have more than one Spring Data module in your application, if you accessed a relational database in the same service layer as your graph database. -Updating two object mapping frameworks is not fun. -Relying on an embedded database configured through Spring Data itself:: -The embedded database in a SDN+OGM project is configured by Neo4j-OGM. -Say you want to upgrade from Neo4j 3.0 to 3.5, you can't without upgrading your whole application. -Why is that? -As you chose to embed a database into your application, you tied yourself into the modules that configure this embedded database. -To have another, embedded database version, you have to upgrade the module that configured it, because the old one does not support the new database. -As there is always a Spring Data version corresponding to Neo4j-OGM, you would have to upgrade that as well. -Spring Data however depends on Spring Framework and then the arguments from the first bullet apply. -Being unsure about which building blocks to include:: -It's not easy to get the terms right. -We wrote the building blocks of an SDN+OGM setting https://michael-simons.github.io/neo4j-examples-and-tips/what_are_the_building_blocks_of_sdn_and_ogm.html[here]. -It may be so that all of them have been added by coincidence and you're dealing with a lot of conflicting dependencies. - -TIP: Backed by those observations, we recommend to make sure you're using only the Bolt or http transport in your current application before switching from SDN+OGM to SDN. -Thus, your application and the access layer of your application is to a large extent independent of the database's version. -From that state, consider moving from SDN+OGM to SDN. -

-This is where `@Id` comes into play. -`@Id` marks an attribute of the class to be the unique identifier of the object. -That unique identifier is in an optimal world a unique business key or in other words, a natural key. -`@Id` can be used on all attributes with a supported simple type. - -Natural keys are however pretty hard to find. -Peoples names for example are seldom unique, change over time or worse, not everyone has a first and last name. - -We therefore support two different kind of _surrogate keys_. - -On an attribute of type `String`, `long` or `Long`, `@Id` can be used with `@GeneratedValue`. -`Long` and `long` maps to the Neo4j internal id. -`String` maps to the _elementId_ that is available since Neo4j 5. -Both are *not* a property on a node or relationship and usually not visible, to the attribute and allows SDN to retrieve individual instances of the class. - -`@GeneratedValue` provides the attribute `generatorClass`. -`generatorClass` can be used to specify a class implementing `IdGenerator`. -An `IdGenerator` is a functional interface and its `generateId` takes the primary label and the instance to generate an Id for. -We support `UUIDStringGenerator` as one implementation out of the box. -

-If, e.g., two transactions in different threads want to modify the same object with version `x`, the first operation will get successfully persisted to the database. -At this moment, the version field will get incremented, so it is `x+1`. -The second operation will fail with a `OptimisticLockingFailureException` because it wants to modify the object with the version `x` -that does not exist anymore in the database. -In such cases the operation needs to get retried, beginning with a fresh fetch of the object with the current version from the database. - -The `@Version` attribute is also mandatory if xref:object-mapping/mapping-ids.adoc#mapping.id-handling.business-key[business ids] are used. -Spring Data Neo4j will check this field to determine if the entity is new or has already been persisted before. -

The Neo4j extension will dutiful create a new connection and driver - * instance, but Spring won't ever use it. - * - * @author Michael J.
