implicit session

An Full definition for Aura Graph Analytics session (opens in a new tab)A managed, temporary compute environment that holds a projection and runs algorithms against it. created together with its Full definition for projection (opens in a new tab)An in-memory copy of part of your database that graph algorithms run against. You choose which nodes and relationships it holds., in a single call.

Example

One call, which starts the session and scans the projection into it.

cypher
CALL gds.graph.project(
  'directors-graph',
  ['Director', 'Movie'],
  'DIRECTED',
  {
    memory: '2GB',
    ttl: 'PT30M'
  }
)
YIELD nodeCount, relationshipCount
RETURN nodeCount, relationshipCount

The config map carries memory and ttl where it would otherwise carry the id of a session that already exists.
