Index Mapping tool

Introduced 2.12

This is an experimental feature and is not recommended for use in a production environment. For updates on the progress of the feature or if you want to leave feedback, see the associated GitHub issue.

The IndexMappingTool retrieves mapping and setting information for indexes in your cluster.

Step 1: Register a flow agent that will run the IndexMappingTool

A flow agent runs a sequence of tools in order and returns the last tool’s output. To create a flow agent, send the following register agent request:

POST /_plugins/_ml/agents/_register
{
  "name": "Test_Agent_For_IndexMapping_tool",
  "type": "flow",
  "description": "this is a test agent for the IndexMappingTool",
  "tools": [
      {
      "type": "IndexMappingTool",
      "name": "DemoIndexMappingTool",
      "parameters": {
        "index": "${parameters.index}",
        "input": "${parameters.question}"
      }
    }
  ]
}

copy

For parameter descriptions, see Register parameters.

OpenSearch responds with an agent ID:

{
  "agent_id": "9X7xWI0Bpc3sThaJdY9i"
}

Step 2: Run the agent

Before you run the agent, make sure that you add the sample OpenSearch Dashboards Sample eCommerce orders dataset. To learn more, see Adding sample data.

Then, run the agent by sending the following request and providing the index name and the question:

POST /_plugins/_ml/agents/9X7xWI0Bpc3sThaJdY9i/_execute
{
  "parameters": {
    "index": [ "sample-ecommerce" ],
    "question": "What fields are in the sample-ecommerce index?"
  }
}

copy

OpenSearch returns the mappings and settings for the specified index:

{
  "inference_results": [
    {
      "output": [
        {
          "name": "response",
          "result": """index: sample-ecommerce
mappings:
properties={items_purchased_failure={type=integer}, items_purchased_success={type=integer}, order_id={type=integer}, timestamp={type=date}, total_revenue_usd={type=integer}}
settings:
index.creation_date=1706752839713
index.number_of_replicas=1
index.number_of_shards=1
index.provided_name=sample-ecommerce
index.replication.type=DOCUMENT
index.uuid=UPYOQcAfRGqFAlSxcZlRjw
index.version.created=137217827
"""
        }
      ]
    }
  ]
}
