Method: projects.instances.databaseOperations.list

Lists database longrunning-operations. A database operation has a name of the form projects/<project>/instances/<instance>/databases/<database>/operations/<operation>. The long-running operation metadata field type metadata.type_url describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations.

HTTP request


The URL uses gRPC Transcoding syntax.

Path parameters



Required. The instance of the database operations. Values are of the form projects/<project>/instances/<instance>.

Authorization requires the following IAM permission on the specified resource parent:

  • spanner.databaseOperations.list

Query parameters



An expression that filters the list of returned operations.

A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: <, >, <=, >=, !=, =, or :. Colon : is the contains operator. Filter rules are not case sensitive.

The following fields in the Operation are eligible for filtering:

  • name - The name of the long-running operation
  • done - False if the operation is in progress, else true.
  • metadata.@type - the type of metadata. For example, the type string for RestoreDatabaseMetadata is
  • metadata.<field_name> - any field in metadata.value. metadata.@type must be specified first, if filtering on metadata fields.
  • error - Error associated with the long-running operation.
  • response.@type - the type of response.
  • response.<field_name> - any field in response.value.

You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic. However, you can specify AND, OR, and NOT logic explicitly.

Here are a few examples:

  • done:true - The operation is complete.
  • ( AND \ (metadata.source_type:BACKUP) AND \ (metadata.backup_info.backup:backup_howl) AND \ ( AND \ (metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND \ (error:*) - Return operations where:
    • The operation's metadata type is RestoreDatabaseMetadata.
    • The database is restored from a backup.
    • The backup name contains "backup_howl".
    • The restored database's name contains "restored_howl".
    • The operation started before 2018-03-28T14:50:00Z.
    • The operation resulted in an error.


Number of operations to be returned in the response. If 0 or less, defaults to the server's maximum allowed page size.



If non-empty, pageToken should contain a nextPageToken from a previous ListDatabaseOperationsResponse to the same parent and with the same filter.

Request body

The request body must be empty.

Response body

If successful, the response body contains data with the following structure:

The response for databaseOperations.list.

JSON representation
  "operations": [
      object (Operation)
  "nextPageToken": string

object (Operation)

The list of matching database long-running operations. Each operation's name will be prefixed by the database's name. The operation's metadata field type metadata.type_url describes the type of the metadata.



nextPageToken can be sent in a subsequent databaseOperations.list call to fetch more of the matching metadata.
