The most significant change in memory estimation is that in GDS to estimate an operation you suffix it with .estimate while in GA the operation had to be passed as parameter to algo.memrec.

Native Projections:

 
CALL algo.memrec(
  'MyLabel',
  'MY_RELATIONSHIP_TYPE',
  'graph.load'
)
 
CALL gds.graph.create.estimate(
  'MyLabel',
  'MY_RELATIONSHIP_TYPE'
)

Cypher Projections:

 
CALL algo.memrec(
  'MATCH (n:MyLabel) RETURN id(n) AS id',
  'MATCH (s)-[r:MY_RELATIONSHIP_TYPE]->(t)
   RETURN id(s) AS source, id(t) AS target',
  'graph.load',
  {
    graph: 'cypher'
  }
)
 
CALL gds.graph.create.cypher.estimate(
  'MATCH (n:MyLabel) RETURN id(n) AS id',
  'MATCH (s)-[r:MY_RELATIONSHIP_TYPE]->(t)
   RETURN id(s) AS source, id(t) AS target'
)
