• Extend Agtype
  • Support for Numeric types.
  • Support for Edge types.
  • Support for Path types.
• Type Casting
  • Type annotations ‘::’ can be added to scalar values, arrays and objects.
  • Casting to a numeric ‘::numeric’ from an integer, float, or string.
  • Casting to a float ‘::float’ from an integer, numeric, or string.
  • Addition of float constants (inf, -inf, NaN) to string input and output.
  • Casting to a vertex ‘::vertex’ from an agtype object.
  • Casting to an edge “::edge’ from an agtype object.
  • Casting to a path ‘::path’ from an agtype array.
• Scalar Functions
  • id() Returns the id of a vertex or edge.
  • start_id() Returns the start id of a vertex or edge.
  • end_id() Returns the end id of a vertex or edge.
  • type() Returns the relationship name of an edge.
  • properties() Returns the properties object of a vertex or edge.
  • head() Returns the head of a list.
  • last() Returns the last element in a list.
  • length() Returns the length of a path.
  • size() Returns the length of a string or the number of elements in a list.
  • startNode() Returns the start vertex for an edge.
  • endNode() Returns the end vertex for an edge.
  • timestamp() Returns the system time in milliseconds from Epoch.
  • toBoolean() Converts a string to a boolean.
  • toFloat() Converts an integer, numeric, or string to a float.
  • toInteger() Converts a float, numeric, or string to an integer.
  • coalesce() Returns the first non null expression in a list of expressions.
• Labels for Vertices/Edges
  • Newly created Edges can be assigned with a label.
  • Newly created Labels vertices do not require a label.
• Improve Match Clause
  • Support Edges - Match clauses support paths.
  • Support Patterns - Match clauses support multiple paths.
  • Support Vertices with no variable assignment.
  • Support Edges and Paths with variable assignment.
• Improve Create Clause
  • Support Edges - Create Clause supports paths.
  • Support Patterns - Create Clause supports multiple paths.
