I built an open-source tool to query on-prem databases and DynamoDB in plain English

The Problem

If you've ever worked in a hybrid cloud environment, you know the pain.

You've got legacy data sitting on-premise — MySQL, PostgreSQL, Oracle, SQL Server — and you need it in AWS. So you write a custom sync script. Then another one. Then a cron job breaks at 2am. Then someone changes a schema and the whole pipeline falls apart.

I've been in that situation too many times. So I built IntelliHybrid.

What is IntelliHybrid?

IntelliHybrid is an open-source Python framework that creates a secure, bidirectional sync between your on-premise databases and AWS DynamoDB — with an AI layer on top that lets you query your data in plain English.

No more writing FilterExpression and KeyConditionExpression by hand. Just ask.

result = await assistant.chat("Show me all orders from customer C-001")
result = await assistant.chat("How many products have stock below 10?")
result = await assistant.chat("Find users who signed up this month")

It figures out the right DynamoDB operation — query, scan, or get_item — and returns live data.

Core Features

🔄 Bidirectional Sync

Data flows both ways — on-prem → DynamoDB and DynamoDB → on-prem — on a configurable schedule.

intellihybrid sync --mode bidirectional --interval 60

🔐 Security First

• KMS-encrypted DynamoDB tables by default
• TLS 1.3 for all data in transit
• Least-privilege IAM roles auto-generated per table
• Secrets via environment variables or AWS Secrets Manager — never in config files

⚡ Auto-Provisioning

Define your tables in a simple YAML config and IntelliHybrid creates everything in AWS for you.

dynamodb:
  tables:
    - name: orders-table
      partition_key: { name: orderId, type: S }
      sort_key: { name: customerId, type: S }
      billing_mode: PAY_PER_REQUEST

🤖 AI-Generated Schema Docs

One call produces a full data dictionary — useful for onboarding, compliance, or just understanding what's in a table.

dictionary = await intel.generate_data_dictionary("orders-table")

Output:

# Data Dictionary: `orders-table`

| Attribute       | Type | Description                                       |
|-----------------|------|---------------------------------------------------|
| orderId 🔑 PK   | S    | Unique identifier for each order transaction      |
| customerId 🔑 SK| S    | References the customer — links to users-table PK |
| status          | S    | Fulfillment state: processing, shipped, delivered |
| total           | N    | Order value in USD cents                          |
| createdAt       | N    | Unix timestamp, used for date-range queries       |

Getting Started

pip install intellihybrid
intellihybrid init --config config/config.yaml
intellihybrid sync --mode bidirectional

Setup takes about 5 minutes.
