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.

​
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.
If you installed MindsDB locally via pip, you need to install all handler dependencies manually. To do so, go to the handler’s folder (mindsdb/integrations/handlers/dynamodb_handler) and run this command: pip install -r requirements.txt.

​
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.
