merge
The (alias:Label {property: $property, ...}) pattern a store MERGEs on.
Label and property names are this object's own compile-time constants, and every value is a bound parameter named after its property, so nothing caller-derived is assembled into Cypher. The parameter names line up with the bind maps in LineageRowMappers.
Return
The pattern text, ready to follow a MERGE.
Parameters
alias
The variable the pattern binds the node to.
label
One of the labels above.
