RDS
RDS — spins up real Postgres/MySQL/MariaDB/Aurora containers, plus the RDS Proxy control plane. Control-plane is emulated; data-plane is a real database.
Quick start
import boto3
rds = boto3.client("rds", endpoint_url="http://localhost:4566",
region_name="us-east-1",
aws_access_key_id="test", aws_secret_access_key="test")
rds.create_db_instance(DBInstanceIdentifier="db",
Engine="postgres", EngineVersion="15",
MasterUsername="admin", MasterUserPassword="pw123456",
DBInstanceClass="db.t3.micro", AllocatedStorage=20)
Supported operations
71 operations exposed by this service as of MiniStack 1.5.24. Extracted directly from the handler dispatch in the source module.

CloudFormation
The CloudFormation engine provisions these resource types via this service:
AWS::RDS::DBCluster
AWS::RDS::DBClusterParameterGroup
AWS::RDS::DBInstance
AWS::RDS::DBParameterGroup
AWS::RDS::DBSubnetGroup
See CloudFormation engine for intrinsic support and lifecycle details.
Known limitations
- Backup/restore APIs return success but the underlying snapshots aren't actual Postgres/MySQL dumps.
- Host port is allocated starting at RDS_BASE_PORT (default 15432).
- DB parameter groups reach the server for standalone MySQL and MariaDB instances only (startup options, and SET GLOBAL for immediate changes to dynamic parameters); parameter names and values are not validated against the engine's list, and formula values are not evaluated.
- RDS Proxy is control-plane metadata only — proxies, endpoints and target groups round-trip with the documented shapes, but nothing listens on the proxy endpoint hostname.
- IAM database authentication covers MySQL and Aurora MySQL 8.0/8.4 (not MariaDB or PostgreSQL): with IAMDatabaseAuthenticationEnabled on the instance or cluster, a user created IDENTIFIED WITH AWSAuthenticationPlugin AS 'RDS' logs in with a generate-db-auth-token token over mysql_clear_password. With AUTH=true the token and the rds-db:connect policy are verified; otherwise any token is accepted.
