executeGremlinQuery

This commands executes a Gremlin query. Amazon Neptune is compatible with Apache TinkerPop3 and Gremlin, so you can use the Gremlin traversal language to query the graph, as described under The Graph in the Apache TinkerPop3 documentation. More details can also be found in Accessing a Neptune graph with Gremlin.

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 enables one of the following IAM actions in that cluster, depending on the query:

• neptune-db:ReadDataViaQuery

• neptune-db:WriteDataViaQuery

• neptune-db:DeleteDataViaQuery

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