This is the implementation of the DynamoDB data handler for MindsDB. Amazon DynamoDB is a fully managed, serverless, key-value NoSQL database designed to run high-performance applications at any scale. DynamoDB offers built-in security, continuous backups, automated multi-region replication, in-memory caching, and data export tools.

​
Prerequisites

Before proceeding, ensure the following prerequisites are met:
  1. Install MindsDB locally via Docker or use MindsDB Cloud.
  2. To connect Amazon DynamoDB to MindsDB, install the required dependencies following this instruction.
  3. Install or ensure access to Amazon DynamoDB.

​
Implementation

This handler is implemented using boto3, the AWS SDK for Python. The required arguments to establish a connection are as follows:
  • aws_access_key_id is the AWS access key.
  • aws_secret_access_key is the AWS secret access key.
  • region_name is the AWS region.

​
Usage

In order to make use of this handler and connect to the DynamoDB database in MindsDB, the following syntax can be used: 
CREATE DATABASE dynamodb_datasource
WITH
    engine = 'dynamodb',
    parameters = {
      "aws_access_key_id": "PCAQ2LJDOSWLNSQKOCPW",
      "aws_secret_access_key": "U/VjewPlNopsDmmwItl34r2neyC6WhZpUiip57i",
      "region_name": "us-east-1"
    };
You can use this established connection to query your table as follows: 
SELECT *
FROM dynamodb_datasource.example_tbl;
Queries to DynamoDB can be issued in PartiQL using this handler.
