ListOpenCypherQueries

Lists active openCypher queries. See Neptune openCypher status endpoint for more information.

When invoking this operation in a Neptune cluster that has IAM authentication enabled, the IAM user or role making the request must have a policy attached that allows the neptune-db:GetQueryStatus IAM action in that cluster.

Note that the neptune-db:QueryLanguage:OpenCypher IAM condition key can be used in the policy document to restrict the use of openCypher queries (see Condition keys available in Neptune IAM data-access policy statements).
