Alibaba Cloud RDS Skill

Manage RDS relational database service via the @alicloud/rds20140815 TypeScript SDK.

Prerequisites

npm install @alicloud/rds20140815 @alicloud/openapi-core @darabonba/typescript

export ALIBABA_CLOUD_ACCESS_KEY_ID="<your-key-id>"
export ALIBABA_CLOUD_ACCESS_KEY_SECRET="<your-key-secret>"

See scripts/setup_client.ts for a reusable client factory, and references/quickstart.md for full setup including endpoints, database engines, instance categories, charge types, pagination, and async polling.

Client Initialization

import Client from '@alicloud/rds20140815';
import { Config } from '@alicloud/openapi-core';

const client = new Client(new Config({
  accessKeyId: process.env.ALIBABA_CLOUD_ACCESS_KEY_ID,
  accessKeySecret: process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET,
  endpoint: 'rds.aliyuncs.com',
  regionId: 'cn-hangzhou',
}));

Core Patterns

RPC-Style with DBInstanceId

Most APIs require DBInstanceId as the primary identifier:

import * as models from '@alicloud/rds20140815/dist/models';

const { body } = await client.describeDBInstanceAttribute(
  new models.DescribeDBInstanceAttributeRequest({
    DBInstanceId: 'rm-bp1xxxxxxxxxxxxx',
  })
);

Page-Based Pagination

let pageNumber = 1;
let all: any[] = [];
while (true) {
  const { body } = await client.describeDBInstances(new models.DescribeDBInstancesRequest({
    regionId: 'cn-hangzhou', pageSize: 100, pageNumber,
  }));
  all.push(...(body.items?.DBInstance || []));
  if (all.length >= (body.totalRecordCount || 0)) break;
  pageNumber++;
}

Async Operation Polling

Many operations are async — poll instance status until target state:

while (true) {
  const { body } = await client.describeDBInstanceAttribute(
    new models.DescribeDBInstanceAttributeRequest({ DBInstanceId: instanceId })
  );
  const status = body.items?.DBInstanceAttribute?.[0]?.DBInstanceStatus;
  if (status === 'Running') break;
  await new Promise(r => setTimeout(r, 10000));
}

Multi-Engine Support

RDS supports MySQL, PostgreSQL, SQL Server, and MariaDB. Specify engine at creation:

const { body } = await client.createDBInstance(new models.CreateDBInstanceRequest({
  regionId: 'cn-hangzhou',
  engine: 'MySQL',       // MySQL | PostgreSQL | SQLServer | MariaDB
  engineVersion: '8.0',
  DBInstanceClass: 'mysql.n2m.small.2c',
  DBInstanceStorage: 20,
  DBInstanceNetType: 'Intranet',
  payType: 'Postpaid',
  securityIPList: '10.0.0.0/8', // WARNING: never use 0.0.0.0/0 in production
  DBInstanceStorageType: 'cloud_essd',
}));

Error Handling

try {
  await client.createDBInstance(request);
} catch (err: any) {
  console.error(`Code: ${err.code}, Message: ${err.message}, RequestId: ${err.data?.RequestId}`);
}

Common Workflows

1. Create Instance with Account and Database

createDBInstance → waitForRunning → createAccount → createDatabase → grantAccountPrivilege → modifySecurityIps

2. Read-Only Instance with Database Proxy

createReadOnlyDBInstance → createDBProxy → allocateReadWriteSplittingConnection

3. Backup and Point-in-Time Recovery

modifyBackupPolicy → createBackup → describeBackups → restoreTable

4. Cross-Region Disaster Recovery

modifyInstanceCrossBackupPolicy → describeCrossRegionBackups → createDdrInstance

5. Security Hardening

modifySecurityIps → modifyDBInstanceSSL → modifyDBInstanceTDE → modifySQLCollectorPolicy

6. Parameter Tuning

describeParameterTemplates → describeParameters → modifyParameter → restartDBInstance

7. Performance Monitoring

describeDBInstancePerformance → describeSlowLogRecords → createDiagnosticReport

8. PostgreSQL Major Version Upgrade

upgradeDBInstanceMajorVersionPrecheck → describeUpgradeMajorVersionPrecheckTask → upgradeDBInstanceMajorVersion

See references/workflows.md for detailed workflow examples with full code.

API Reference Quick Index

Load the corresponding reference file for parameter details:

• Instance CRUD/lifecycle/spec/network/pricing: references/instance.md
• Read-only instances/proxy/read-write splitting: references/readonly.md
• Account CRUD/password/privileges: references/account.md
• Database CRUD/charset/collation: references/database.md
• Backup/restore/cross-region DR: references/backup.md
• IP whitelist/SSL/TDE/security groups/masking: references/security.md
• Performance/slow queries/SQL audit/diagnostics: references/monitoring.md
• Parameters/parameter groups/events: references/parameter.md
• Migration/import/export/GAD: references/migration.md
