This page talks about using
algo.memrec to calculate memory requirements, but it doesn't seem to exist on our installation of 3.5.7-enterprise:
Neo.ClientError.Procedure.ProcedureNotFound: There is no procedure with the name `algo.memrec` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
Google is failing me. Is this something that was removed?
