DreamFactory DynamoDB: Instant REST APIs for AWS DynamoDB Without Code
by Kevin McGahey • December 9, 2025
Amazon DynamoDB is a powerful, fully managed NoSQL database service that delivers single-digit millisecond performance at any scale. Yet despite its impressive capabilities, accessing DynamoDB from applications often requires wrestling with verbose SDK code, managing authentication complexities, and implementing repetitive CRUD operations manually.
What if you could eliminate all that boilerplate and instantly expose your DynamoDB tables through a secure, documented REST API in just minutes? That's exactly what DreamFactory's DynamoDB integration delivers.
The DynamoDB Challenge: Power Meets Complexity
DynamoDB is widely adopted for its scalability, performance, and serverless architecture. From session management and gaming leaderboards to IoT time-series data and e-commerce carts, DynamoDB powers critical applications for thousands of organizations.
However, integrating DynamoDB into your applications comes with several challenges:
1. SDK Complexity and Verbose Code
The AWS SDK for DynamoDB, while powerful, requires significant code for even basic operations. A simple query operation can require dozens of lines of code handling:
- AWS credential management
- DynamoDB-specific attribute formatting (AttributeValue structures)
- Expression syntax for queries and filters
- Pagination handling with LastEvaluatedKey
- Error handling for throughput exceptions, validation errors, and more
- Data marshaling and unmarshaling between JSON and DynamoDB's format
2. Multiple Access Patterns Require Custom Development
Each application or service that needs DynamoDB access traditionally requires:
- Custom API endpoints for each operation type
- Authentication and authorization logic
- Request validation and sanitization
- Response formatting and error handling
- API documentation (often manually maintained)
3. Limited Native REST Support
While DynamoDB has a low-level HTTP API, it's not RESTful and requires complex JSON payloads with DynamoDB's specific attribute type notation. This makes direct HTTP access impractical for most applications.
4. Maintenance Overhead
As your DynamoDB schema evolves—adding tables, modifying indexes, or changing access patterns—your custom API code must be updated, tested, and redeployed accordingly.
How DreamFactory Transforms DynamoDB Access
DreamFactory eliminates these challenges by automatically generating a complete, production-ready REST API for your DynamoDB tables with zero code required. Here's how it works:
Step 1: Connect Your DynamoDB Instance
In the DreamFactory admin console, simply:
- Select Connect to Database
- Select AWS DynamoDB
- Provide your AWS credentials (Access Key ID and Secret Access Key)
- Select your AWS region
- Save the API service
That's it. No SDK installation, no code deployment, no configuration files.
Step 2: Your REST API is Ready
DreamFactory immediately generates REST endpoints for all your DynamoDB tables:
GET /api/v2/dynamodb/_table- List all tablesGET /api/v2/dynamodb/_table/{table_name}- Retrieve records with filtering, pagination, and field selectionPOST /api/v2/dynamodb/_table/{table_name}- Create new recordsPATCH /api/v2/dynamodb/_table/{table_name}- Update existing recordsDELETE /api/v2/dynamodb/_table/{table_name}- Delete recordsGET /api/v2/dynamodb/_schema/{table_name}- Get table schema and metadata
Step 3: Automatic Documentation
DreamFactory auto-generates interactive OpenAPI (Swagger) documentation for all endpoints. Access it at:
GET /api/v2/dynamodb?file=openapi- Full OpenAPI specification- API Docs tab in the admin console - Interactive testing interface
The documentation stays automatically synchronized with your DynamoDB schema—no manual updates needed.
Key Features and Capabilities
1. SQL-Like Filtering with DynamoDB Native Support
DreamFactory provides a powerful dual-mode filtering system:
SQL-Style Filters (Simplified)
Use familiar SQL-like syntax that DreamFactory automatically translates to DynamoDB's native filter expressions:
GET /api/v2/dynamodb/_table/users?filter=age>25 AND status='active'
Supported operators include:
- Comparison:
=,!=,>,>=,<,<= - Logical:
AND,OR - Pattern matching:
LIKE,BEGINS WITH - Membership:
IN,NOT IN - Existence:
IS NULL,IS NOT NULL
Native DynamoDB Filters (Advanced)
For advanced use cases, pass DynamoDB's native filter expressions as JSON:
GET /api/v2/dynamodb/_table/users?filter={"age":{">=":25}}
This flexibility lets you start simple and use advanced DynamoDB features when needed.
2. Intelligent Pagination
DynamoDB uses token-based pagination with LastEvaluatedKey, which can be complex to implement. DreamFactory handles this automatically:
GET /api/v2/dynamodb/_table/orders?limit=100
Response includes a next token for pagination:
{
"resource": [/* 100 records */],
"meta": {
"next": "eyJpZCI6IjEyMzQ1In0=",
"count": 100
}
}
Continue pagination with the next token:
GET /api/v2/dynamodb/_table/orders?limit=100&offset=eyJpZCI6IjEyMzQ1In0=
DreamFactory automatically handles composite keys, base64 encoding, and key structure formatting—complexity hidden from your application.
3. Field Selection (Projection)
Reduce bandwidth and improve performance by selecting only the fields you need:
GET /api/v2/dynamodb/_table/products?fields=id,name,price
DreamFactory translates this to DynamoDB's ProjectionExpression, optimizing the query automatically.
4. Automatic Data Format Translation
DynamoDB's native format uses verbose attribute type notation:
{
"id": {"S": "user123"},
"age": {"N": "30"},
"tags": {"SS": ["premium", "verified"]}
}
DreamFactory automatically marshals data to simple JSON:
{
"id": "user123",
"age": 30,
"tags": ["premium", "verified"]
}
Your applications work with clean, intuitive JSON—no marshaling logic required.
5. Comprehensive Security Built-In
Every DreamoDB API is secured by default with DreamFactory's robust security features:
- API Key Authentication: Every request requires a valid API key
- Role-Based Access Control (RBAC): Define granular permissions per table, per operation, even per field
- Row-Level Security: Filter records based on user attributes (e.g.,
user_id = {user.id}) - OAuth 2.0, SAML, LDAP, Active Directory: Enterprise authentication out of the box
- Rate Limiting: Protect against abuse with configurable rate limits per user/role
- Audit Logging: Track every API call with detailed audit trails
Example RBAC configuration for a mobile app:
- Allow
GETonuserstable, fields:id, name, email - Allow
PATCHonuserstable whereid = {user.id}(users can only update themselves) - Deny access to
admin_configtable entirely - Rate limit: 1000 requests per hour per user
6. Server-Side Scripting for Custom Business Logic
Need to add validation, data transformation, or complex business rules? DreamFactory supports pre- and post-processing scripts in PHP, Python, or Node.js:
// Pre-process script (before writing to DynamoDB)
event.request.body.resource.forEach(record => {
// Add timestamp
record.created_at = new Date().toISOString();
// Validate email format
if (!record.email.includes('@')) {
throw 'Invalid email format';
}
// Mask sensitive data
record.ssn_last4 = record.ssn.slice(-4);
delete record.ssn;
});
Scripts execute server-side with full access to request context, user session data, and other DreamFactory services.
7. Batch Operations
DreamFactory supports batch creates, updates, and deletes in a single API call:
POST /api/v2/dynamodb/_table/orders
{
"resource": [
{"order_id": "ORD001", "customer": "Alice", "total": 99.99},
{"order_id": "ORD002", "customer": "Bob", "total": 149.50},
{"order_id": "ORD003", "customer": "Charlie", "total": 75.25}
]
}
DreamFactory efficiently batches these to DynamoDB, handling partial failures and returning detailed results for each record.
8. Virtual Relationships
While DynamoDB is schema-less, many applications have logical relationships between tables. DreamFactory lets you define virtual relationships and fetch related data in a single request:
GET /api/v2/dynamodb/_table/orders?related=customer_info,items
This retrieves orders with related customer and item data joined automatically—no complex application logic needed.

Best Practices for Production
1. Use IAM Roles with Least Privilege
Create dedicated IAM users for DreamFactory with only the DynamoDB permissions needed:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"dynamodb:GetItem",
"dynamodb:PutItem",
"dynamodb:UpdateItem",
"dynamodb:DeleteItem",
"dynamodb:Query",
"dynamodb:Scan",
"dynamodb:DescribeTable",
"dynamodb:ListTables"
],
"Resource": "arn:aws:dynamodb:us-east-1:123456789012:table/*"
}
]
}
2. Enable Caching for Read-Heavy Workloads
Configure Redis caching in DreamFactory to reduce DynamoDB read costs:
- Navigate to API Generation & Connections > dynamodb > Caching
- Enable caching with appropriate TTL (e.g., 300 seconds)
- Monitor cache hit rates and adjust as needed
3. Implement Rate Limiting
Protect your DynamoDB instance from abuse and unexpected costs:
- Set rate limits per role (e.g., 1000 requests/hour for standard users)
- Configure separate limits for batch operations
- Monitor rate limit violations in audit logs
4. Use Environment-Specific API Keys
Create separate API keys for development, staging, and production:
- Development: Higher rate limits, full access for testing
- Staging: Production-like limits, test data isolation
- Production: Strict limits, read-only keys for analytics
5. Monitor and Log Everything
Enable DreamFactory's audit logging to track:
- All API requests (who, what, when, from where)
- Failed authentication attempts
- Rate limit violations
- Slow queries (set thresholds in config)
6. Design for DynamoDB Best Practices
While DreamFactory simplifies access, follow DynamoDB design patterns:
- Use partition keys with high cardinality to avoid hot partitions
- Design sort keys for your query patterns
- Consider Global Secondary Indexes (GSI) for additional access patterns
- Use DreamFactory's filter parameters instead of scanning entire tables
