Returns a paginated list of target engine recommendations for your source databases.

Request Syntax

{ "Filters": [ { "Name": "string", "Values": [ "string" ] } ], "MaxRecords": number, "NextToken": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


Filters applied to the target engine recommendations described in the form of key-value pairs.

Type: Array of Filter objects

Required: No


The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, Fleet Advisor includes a pagination token in the response so that you can retrieve the remaining results.

Type: Integer

Required: No


Specifies the unique pagination token that makes it possible to display the next page of results. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

If NextToken is returned by a previous response, there are more results available. The value of NextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged.

Type: String

Required: No
