Promoting a local index to be the aggregator index for the account

For cross-region search functionality, Resource Explorer provides a streamlined banner workflow that allows you to enable cross-region search with a single click. If you see a Complete setup and enable cross-Region search banner, you can choose Enable cross-Region search in all Regions for automatic setup or Customize Region setup for granular control. Alternatively, you have the option to manually create an aggregator index in one AWS Region by promoting an existing user-owned (local) index from the Settings page . This procedure describes the manual process for promoting a user-owned (local) index to be the aggregator index for the account.

Important

• You can have only one aggregator index in an AWS account. If the account already has an aggregator index, you must first either demote it to a local index or delete it.

• After deleting or changing which Region contains the aggregator index, you must wait 24 hours before you can promote another index to be the aggregator index.

AWS Management Console

To promote a user-owned (local) index to be the aggregator index for the account

1. Primary method - Banner workflow: If you see a Complete setup and enable cross-Region search banner or banner notification, you can use the guided workflow:

   1. For automatic setup across all regions, choose Enable cross-Region search in all Regions, or

   2. For customized configuration, choose Customize Region setup to access granular setup options.

2. Alternative method: The Settings page.

   1. Open the Resource Explorer Settings page.

   2. In the Indexes section, select the check box next to the index that you want to promote, and then choose Change index type.

   3. In the Change index type for <Region name> dialog, choose aggregator index, and then choose Save changes.

AWS CLI

To promote a user-owned (local) index to be the aggregator index for the account

The following example command updates the index in the specified AWS Region from type LOCAL to type AGGREGATOR. You must call the operation from the AWS Region that you want to contain the aggregator index. For information about the banner workflow option, see the Console tab above.

$ aws resource-explorer-2 update-index-type \
    --arn arn:aws:resource-explorer-2:us-east-1:123456789012:index/1a2b3c4d-5d6e-7f8a-9b0c-abcd11111111 \
    --type AGGREGATOR \
    --region us-east-1
{
    "Arn":"arn:aws:resource-explorer-2:us-east-1:123456789012:index/1a2b3c4d-5d6e-7f8a-9b0c-abcd11111111",
    "LastUpdatedAt":"2022-07-13T18:41:58.799Z",
    "State":"UPDATING",
    "Type":"AGGREGATOR"
}

The operation works asynchronously and starts with State set to UPDATING. To check if the operation has completed, you can run the following command and look for the value ACTIVE in the State response field. You must run this command in the Region the contains the index you want to check.

$ aws resource-explorer-2 get-index --region us-east-1
{
    "Arn": "arn:aws:resource-explorer-2:us-east-1:123456789012:index/1a2b3c4d-5d6e-7f8a-9b0c-abcd11111111",
    "CreatedAt": "2022-10-12T21:31:37.277000+00:00",
    "LastUpdatedAt": "2022-10-12T21:31:37.677000+00:00",
    "ReplicatingFrom": [
        "us-west-2",
        "us-east-2",
        "us-west-1"
    ],
    "State": "ACTIVE",
    "Tags": {},
    "Type": "AGGREGATOR"
}
