  title: Amazon Neptune openCypher Explain then Execute
  summary: Inspect an openCypher query's execution plan, then run it for real.
  description: >-
    A query-tuning workflow for openCypher. It first retrieves the execution plan
    for a query through the explain endpoint, using the supplied explain mode,
    without running the query against the data, then executes the same query so a
    caller can compare the planned and actual behaviour. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
