Struct EdgeSet 

pub struct EdgeSet {
    pub src_label: String,
    pub edge_type: String,
    pub dst_label: String,
    pub src_id_column: String,
    pub dst_id_column: String,
    pub edge_key_props: Vec<String>,
    pub replace_outgoing: bool,
    pub batch: RecordBatch,
}

Relationships to upsert: batch must hold src and dst columns with the id values of the endpoint nodes; remaining columns become properties.

Fields

src_label: String

edge_type: String

dst_label: String

src_id_column: String

Id column on the endpoint nodes that src/dst values refer to.

dst_id_column: String

edge_key_props: Vec<String>

Property columns whose values participate in the relationship MERGE key. Empty (the default, and every historical producer) keeps the original behaviour: MERGE (a)-[e:type]->(b) collapses to ONE edge per (src, type, dst). When non-empty, those properties are folded into the relationship pattern — MERGE (a)-[e:type {p: r.props.p}]->(b) — so distinct property combinations survive as PARALLEL edges between the same endpoints (e.g. two WORKS_AT edges with different since). Each name must be a property column of batch (i.e. not src/dst).

replace_outgoing: bool

One edge of this type per source node — the row is the truth: before the upsert, the source node’s other outgoing edges of this type (to any other target, or all of them when dst is null — the foreign key was cleared) are deleted. This is how a changed foreign key drops its old edge whatever the changelog carried for the old row. Set by fk_edges steps; ignored when edge_key_props is non-empty (parallel edges are the point).

batch: RecordBatch
