modify_db_instance_spec
Change RDS instance specifications to adjust compute power, storage, or payment type for scaling database performance or cost optimization.
Instructions

pay_type: Instance payment type. Values: Postpaid, Prepaid, Serverless.
effective_time: When the new configuration takes effect. Values: Immediate, MaintainTime, ScheduleTime.
switch_time: Scheduled switch time in format: yyyy-MM-ddTHH:mm:ssZ (UTC time).
switch_time_mode: Switch time mode. Values: Immediate, MaintainTime, ScheduleTime.
source_biz: Source business type.
dedicated_host_group_id: Dedicated host group ID.
zone_id: Zone ID.
vswitch_id: VSwitch ID.
category: Instance category.
instance_network_type: Instance network type.
direction: Specification change direction. Values: UP, DOWN.
auto_pause: Whether to enable auto pause for Serverless instances.
max_capacity: Maximum capacity for Serverless instances.
min_capacity: Minimum capacity for Serverless instances.
switch_force: Whether to force switch for Serverless instances.
client_token: Client token for idempotency, max 64 ASCII characters.
Returns:
Dict[str, Any]: The response containing the request ID.Input Schema

Implementation Reference
- The handler function that implements the 'modify_db_instance_spec' MCP tool by constructing and sending a ModifyDBInstanceSpecRequest to the Alibaba Cloud RDS SDK client.
