%% @doc Amazon Web Services Resource Explorer is a resource search and
%% discovery service.
%%
%% By using Resource Explorer, you can explore your resources using an
%% internet search engine-like experience. Examples of resources include
%% Amazon Relational Database Service (Amazon RDS) instances, Amazon Simple
%% Storage Service (Amazon S3) buckets, or Amazon DynamoDB tables. You can
%% search for your resources using resource metadata like names, tags, and
%% IDs. Resource Explorer can search across all of the Amazon Web Services
%% Regions in your account in which you turn the service on, to simplify your
%% cross-Region workloads.
%%
%% Resource Explorer scans the resources in each of the Amazon Web Services
%% Regions in your Amazon Web Services account in which you turn on Resource
%% Explorer. Resource Explorer creates and maintains an index in each Region,
%% with the details of that Region's resources.
%%
%% You can search across all of the indexed Regions in your account by
%% designating one of your Amazon Web Services Regions to contain the
%% aggregator index for the account. When you promote a local index in a
%% Region to become the aggregator index for the account, Resource Explorer
%% automatically replicates the index information from all local indexes in
%% the other Regions to the aggregator index. Therefore, the Region with the
%% aggregator index has a copy of all resource information for all Regions in
%% the account where you turned on Resource Explorer. As a result, views in
%% the aggregator index Region include resources from all of the indexed
%% Regions in your account.
%%
%% For more information about Amazon Web Services Resource Explorer,
%% including how to enable and configure the service, see the Amazon Web
%% Services Resource Explorer User Guide.

%% @doc Turns on Amazon Web Services Resource Explorer in the Amazon Web
%% Services Region in which you called this operation by creating an index.
%%
%% Resource Explorer begins discovering the resources in this Region and
%% stores the details about the resources in the index so that they can be
%% queried by using the `Search' operation. You can create only one index
%% in a Region.
%%
%% This operation creates only a local index. To promote the local index in
%% one Amazon Web Services Region into the aggregator index for the Amazon
%% Web Services account, use the `UpdateIndexType' operation. For more
%% information, see Turning on cross-Region search by creating an aggregator
%% index in the Amazon Web Services Resource Explorer User Guide.
%%
%% For more details about what happens when you turn on Resource Explorer in
%% an Amazon Web Services Region, see Turn on Resource Explorer to index your
%% resources in an Amazon Web Services Region in the Amazon Web Services
%% Resource Explorer User Guide.
%%
%% If this is the first Amazon Web Services Region in which you've
%% created an index for Resource Explorer, then this operation also creates a
%% service-linked role in your Amazon Web Services account that allows
%% Resource Explorer to enumerate your resources to populate the index.
%%
%% <ul> <li> Action: `resource-explorer-2:CreateIndex'
%%
%% Resource: The ARN of the index (as it will exist after the operation
%% completes) in the Amazon Web Services Region and account in which
%% you're trying to create the index. Use the wildcard character
%% (`*') at the end of the string to match the eventual UUID. For
%% example, the following `Resource' element restricts the role or user
%% to creating an index in only the `us-east-2' Region of the specified
%% account.
%%
%% `&quot;Resource&quot;:
%% &quot;arn:aws:resource-explorer-2:us-west-2:&lt;account-id&gt;:index/*&quot;'
%%
%% Alternatively, you can use `&quot;Resource&quot;: &quot;*&quot;' to
%% allow the role or user to create an index in any Region.
%%
%% </li> <li> Action: `iam:CreateServiceLinkedRole'
%%
%% Resource: No specific resource (*).
%%
%% This permission is required only the first time you create an index to
%% turn on Resource Explorer in the account. Resource Explorer uses this to
%% create the service-linked role needed to index the resources in your
%% account. Resource Explorer uses the same service-linked role for all
%% additional indexes you create afterwards.

%% @doc Changes the type of the index from one of the following types to the
%% other.
%%
%% For more information about indexes and the role they perform in Amazon Web
%% Services Resource Explorer, see Turning on cross-Region search by creating
%% an aggregator index in the Amazon Web Services Resource Explorer User
%% Guide.
%%
%% <ul> <li> `AGGREGATOR' index type
%%
%% The index contains information about resources from all Amazon Web
%% Services Regions in the Amazon Web Services account in which you've
%% created a Resource Explorer index. Resource information from all other
%% Regions is replicated to this Region's index.
%%
%% When you change the index type to `AGGREGATOR', Resource Explorer
%% turns on replication of all discovered resource information from the other
%% Amazon Web Services Regions in your account to this index. You can then,
%% from this Region only, perform resource search queries that span all
%% Amazon Web Services Regions in the Amazon Web Services account. Turning on
%% replication from all other Regions is performed by asynchronous background
%% tasks. You can check the status of the asynchronous tasks by using the
%% `GetIndex' operation. When the asynchronous tasks complete, the
%% `Status' response of that operation changes from `UPDATING' to
%% `ACTIVE'. After that, you can start to see results from other Amazon
%% Web Services Regions in query results. However, it can take several hours
%% for replication from all other Regions to complete.
%%
%% You can have only one aggregator index per Amazon Web Services account.
%% Before you can promote a different index to be the aggregator index for
%% the account, you must first demote the existing aggregator index to type
%% `LOCAL'.
%%
%% </li> <li> `LOCAL' index type
%%
%% The index contains information about resources in only the Amazon Web
%% Services Region in which the index exists. If an aggregator index in
%% another Region exists, then information in this local index is replicated
%% to the aggregator index.
%%
%% When you change the index type to `LOCAL', Resource Explorer turns off
%% the replication of resource information from all other Amazon Web Services
%% Regions in the Amazon Web Services account to this Region. The aggregator
%% index remains in the `UPDATING' state until all replication with other
%% Regions successfully stops. You can check the status of the asynchronous
%% task by using the `GetIndex' operation. When Resource Explorer
%% successfully stops all replication with other Regions, the `Status'
%% response of that operation changes from `UPDATING' to `ACTIVE'.
%% Separately, the resource information from other Regions that was
