promote_read_replica#

RDS.Client.promote_read_replica(**kwargs)#

Promotes a read replica DB instance to a standalone DB instance.

Note

Backup duration is a function of the amount of changes to the database since the previous backup. If you plan to promote a read replica to a standalone instance, we recommend that you enable backups and complete at least one backup prior to promotion. In addition, a read replica cannot be promoted to a standalone instance when it is in the backing-up status. If you have enabled backups on your read replica, configure the automated backup window so that daily backups do not interfere with read replica promotion.
This command doesn’t apply to Aurora MySQL, Aurora PostgreSQL, or RDS Custom.

Request Syntax

response = client.promote_read_replica(
    DBInstanceIdentifier='string',
    BackupRetentionPeriod=123,
    PreferredBackupWindow='string'
)

Parameters:

DBInstanceIdentifier (string) –
[REQUIRED]

The DB instance identifier. This value is stored as a lowercase string.

Constraints:
- Must match the identifier of an existing read replica DB instance.
Example: mydbinstance
BackupRetentionPeriod (integer) –
The number of days for which automated backups are retained. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

Default: 1

Constraints:
- Must be a value from 0 to 35.
- Can’t be set to 0 if the DB instance is a source to read replicas.
PreferredBackupWindow (string) –
The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter.

The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Web Services Region. To see the time blocks available, see Adjusting the Preferred Maintenance Window in the Amazon RDS User Guide.

Constraints:
- Must be in the format hh24:mi-hh24:mi.
- Must be in Universal Coordinated Time (UTC).
- Must not conflict with the preferred maintenance window.
- Must be at least 30 minutes.

Return type:

dict

Returns:
