CDK construct for creating an analysis environment using DuckDB for S3 data

CloudDuck is a CDK construct for simple and easy-to-use analysis environment for S3 data, featuring DuckDB with built-in authentication.

By simply deploying the Construct, you can launch a SaaS that provides an analytics dashboard like the one shown below. User authentication for access is implemented using Cognito, ensuring that only authorized users can log in.

Use Cases

• When you want to request data analysis on S3 using DuckDB but prefer not to issue S3 access credentials to the analysts.
• When you want to minimize the costs incurred from downloading large amounts of S3 data to local storage.

Architecture

Installation

npm i cloud-duck

Setup

Deploy

You can deploy the CloudDuck with the following code in the CDK stack.

import { Size } from 'aws-cdk-lib';
import { CloudDuck } from 'cloud-duck';

declare const logBucket: s3.IBucket;

new CloudDuck(this, 'CloudDuck', {
  // The S3 bucket to analyze
  // CloudDuck can access to all of the buckets in the account by default.
  // If you want to restrict the access, you can use the targetBuckets property.
  targetBuckets: [logBucket],
  // The memory size of the Lambda function
  // Default: 1024 MB
  memory: Size.mebibytes(1024),
});

Add user to the Cognito User Pool

Add a user to the Cognito User Pool with the following command.

Usage

Query

You can query the S3 data with SQL.

SELECT * FROM read_csv_auto('s3://your-bucket-name/your-file.csv');
SELECT * FROM parquet_scan('s3://your-bucket-name/your-file.parquet');

Ofcourse, you can store the result as a new table.

CREATE TABLE new_table AS SELECT * FROM read_csv_auto('s3://your-bucket-name/your-file.csv');

Detail usage of DuckDB is available at DuckDB Documentation.

Persistence

All query results are persisted in individual DuckDB files for each user. Therefore, you can freely save your query results without worrying about affecting other users.
