Types ¶
type CockroachDBGraph ¶
type CockroachDBGraph struct {
// contains filtered or unexported fields
}
CockroachDBGraph implements a graph that persists links & edges to a cockroachDB
func NewCockroachDBGraph ¶
func NewCockroachDBGraph(dsn string) (*CockroachDBGraph, error)
NewCockroachDBGraph returns a new CockroachDBGraph instance that connects via provided dsn
func (*CockroachDBGraph) Close ¶
func (c *CockroachDBGraph) Close() error
Close closes the CockroachDB connection or returns an error
func (*CockroachDBGraph) Edges ¶
func (c *CockroachDBGraph) Edges(fromID, toID uuid.UUID, updatedBefore time.Time) (graph.EdgeIterator, error)
Edges returns an iterator for the set of edges whose source vertex IDs belong to the [fromID, toID) range and were last updated before the provided value.
func (*CockroachDBGraph) Links ¶
func (c *CockroachDBGraph) Links(fromID, toID uuid.UUID, accessedBefore time.Time) (graph.LinkIterator, error)
Links returns an iterator for the set of links whose IDs belong to the [fromId, toID] range and were last accessed before the provided value
func (*CockroachDBGraph) RemoveStaleEdges ¶
RemoveStaleEdges removes any edge that originates from the specified link ID and was updated before the specified timestamp.
func (*CockroachDBGraph) UpsertEdge ¶
func (c *CockroachDBGraph) UpsertEdge(edge *graph.Edge) error
UpsertEdge creates a new edge or updates an existing edge.
func (*CockroachDBGraph) UpsertLink ¶
func (c *CockroachDBGraph) UpsertLink(link *graph.Link) error
UpsertLink creates a new link or updates an existing one and persists
