ID of the folder to list clusters in. To get this ID, make a [yandex.cloud.resourcemanager.v1.FolderService.List](../../../../resource-manager/api-ref/grpc/Folder/list.md#List) request. The maximum string length in characters is 50. || || page_size | **int64** The maximum number of results per page to return. If the number of available results is larger than `page_size`, the API returns a [ListClustersResponse.next_page_token](#yandex.cloud.mdb.mysql.v1.ListClustersResponse) that can be used to get the next page of results in the subsequent [ClusterService.List](#List) requests. Acceptable values are 0 to 1000, inclusive. || || page_token | **string** Page token that can be used to iterate through multiple pages of results. To get the next page of results, set `page_token` to the [ListClustersResponse.next_page_token](#yandex.cloud.mdb.mysql.v1.ListClustersResponse) returned by the previous [ClusterService.List](#List) request. The maximum string length in characters is 100. || || filter | **string** A filter expression that selects clusters listed in the response. The expression must specify: 1. The field name. Currently you can only use filtering with the [Cluster.name](#yandex.cloud.mdb.mysql.v1.Cluster) field. 2. An `=` operator. 3. The value in double quotes (`"`). Must be 1-63 characters long and match the regular expression `[a-zA-Z0-9_-]+`. The maximum string length in characters is 1000. || |# ## ListClustersResponse {#yandex.cloud.mdb.mysql.v1.ListClustersResponse} ```json { "clusters": [ { "id": "string", "folder_id": "string",
