Manage thing group indexing

AWS_ThingGroups is the index that contains all of your thing groups. You can use this index to search for groups based on group name, description, attributes, and all parent group names.

Enabling thing group indexing

You can use the thing-group-indexing-configuration setting in the UpdateIndexingConfiguration API to create the AWS_ThingGroups index and control its configuration. You can use the GetIndexingConfiguration API to retrieve the current indexing configuration.

To update the thing group indexing configurations, run the update-indexing-configuration CLI command:

aws iot update-indexing-configuration --thing-group-indexing-configuration thingGroupIndexingMode=ON

You can also update configurations for both thing and thing group indexing in a single command, as follows:

aws iot update-indexing-configuration --thing-indexing-configuration thingIndexingMode=REGISTRY --thing-group-indexing-configuration thingGroupIndexingMode=ON

The following are valid values for thingGroupIndexingMode.

To retrieve the current thing and thing group indexing configurations, run the get-indexing-configuration CLI command:

aws iot get-indexing-configuration

The response of the command looks like the following:

{
   "thingGroupIndexingConfiguration": {
        "thingGroupIndexingMode": "ON"
    }
}

Describing group indexes

To retrieve the current status of the AWS_ThingGroups index, use the describe-index CLI command:

aws iot describe-index --index-name "AWS_ThingGroups"

The response of the command looks like the following:

{
   "indexStatus": "ACTIVE", 
   "indexName": "AWS_ThingGroups", 
   "schema": "THING_GROUPS"
}

AWS IoT builds your index the first time that you indexing. You can't query the index if the indexStatus is BUILDING.

Querying a thing group index

To query data in the index, use the search-index CLI command:

aws iot search-index --index-name "AWS_ThingGroups" --query-string "thingGroupName:mythinggroup*"

Authorization

You can specify the thing groups index as a resource ARN in an AWS IoT policy action, as follows.
