Outlook (Roadmap)

Note: The comments on future releases only contain the added features with respect to the previous release (not a complete description of the release contents).

PRESENT Release 4.2.0 Features:
- Access to Neo4j databases
You can access Neo4j databases in a uniform way, no matter if you access a remote database, an embedded database, or an in-memory database, the only difference is in the initialization part.
- Query-DSL
Fluent API to formulate JCypher expressions in order to query a Neo4J database.
- A Generic Graph Model which is easily navigable and modifyable.
- Mapping of complex business domains to domain graphs.
- Domain Queries Part 1 - Predicate Expressions
Domain Queries provide the power and expressiveness of queries on a graph database, while being formulated on domain objects or on types of domain objects respectively.
- Domain Queries Part 2 - Traversal Expressions.
- Domain Queries Part 3 - Collection Expressions (SELECT, REJECT, COLLECT, UNION, INTERSECTION).
- Improved support for multiple domains in a single database.
- Domain Query Concatenation.
- Basic authentication and authorization.
- Transaction API.
- Generic Domain Model.
- Concurrency support for multi client access to the graph database - optimistic locking.
- Concurrency support - thread-safe invocation of 'IDomainAccess' and domain queries.
- JSON Facade in preparation to access JCypher features from other, possibly remote, systems.
- Store domain queries with the domain.
- Use parameters with Query DSL Expressions.
- Support for Neo4J 3.0.X including the BOLT protocol.
- Some improvements like simple construction of literal lists.
- Code compatibility with Java 1.7 (JCypher since 3.5.0 however is built for Java 1.8. This is required, so that JCypher- embedded and- in-memory db access works with Neo4J 3.0.x ).
- Support for extended Authentication according to Neo4J's Bolt Driver specification.
- Registration of shutdown hooks on IDBAccess instances is made optional.
- Public constructors for IDBAccess implementations allow more flexible configurations.
- Set the planner strategy globally or individually on a per query basis.
- Support for Neo4J 3.4.1
- Fix for minHops(0)
- Collections in the Query API are aware of their component type. This allows expressions like: WHERE.valueOf(path.relations().last().type()).EQUALS("Some_Type") or: WHERE.has(path.nodes().head().label("Some_Label"))
- Support for Neo4J 3.5.x
