ExecuteGremlinProfileQueryCommand

Suggest an Edit

Executes a Gremlin Profile query, which runs a specified traversal, collects various metrics about the run, and produces a profile report as output. See Gremlin profile API in Neptune  for details.

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:ReadDataViaQuery  IAM action in that cluster.

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 ).

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { NeptunedataClient, ExecuteGremlinProfileQueryCommand } from "@aws-sdk/client-neptunedata"; // ES Modules import
// const { NeptunedataClient, ExecuteGremlinProfileQueryCommand } = require("@aws-sdk/client-neptunedata"); // CommonJS import
const client = new NeptunedataClient(config);
const input = { // ExecuteGremlinProfileQueryInput
  gremlinQuery: "STRING_VALUE", // required
  results: true || false,
  chop: Number("int"),
  serializer: "STRING_VALUE",
  indexOps: true || false,
};
const command = new ExecuteGremlinProfileQueryCommand(input);
const response = await client.send(command);
// { // ExecuteGremlinProfileQueryOutput
//   output: new Uint8Array(),
// };
