Transfer label from predicate to vertex

3

for e.g. `MATCH (v) WHERE v.__label__ = "Foo"` the label needs to be updated at the query vertex representing v.

1.0$ -> BigDecimal

fixes #48 - Expose Wcc in unladen_swallow - Add numpy to dev requirements

Comment by @DarthMax in https://github.com/opencypher/cypher-for-apache-spark/pull/820: I would suggest to either find a new name for this operator or converting this into a planner using more general relational operators

We currently limit GraphDDL to support only Relationship types with just one label. However, the spec doesn't have that limitation, only CAPS has. We perform cardinality checks within the GraphDDL...

Add sort mechanism on Graph Collections / Vertices / Edges

1

1. evaluate distributed sorting algorithms 2. pick one (or more) 3. discuss with me 4. implement

* [X] JoinEmbeddingsNode (fixed in #545) * [ ] ExpandEmbeddingsNode

Synchronisation of analytical programs

1

If an analytical program, splits up in two disjoint branches, vertices and edges are not synchronized according their graph membership and possible transformations. We need to think about a concept...
