# cdk-datalake-constructs  <!-- omit in toc -->

***Very experimental until version 1.0.***
This is my attempt at simplifying deploying various datalake strategies in AWS with the CDK.

## Features

- Easy to Start - Create a Datalake in a few lines.
- Easy to Expand - Expand into multiple accounts and into a data mesh.
- Easy to Admin - Initial governance created on deploy.

TypeScript/JavaScript

```sh
$ npm install @randyridgley/cdk-datalake-constructs
```

```sh
$ pip install cdk-datalake-constructs
```

# See more: https://www.nuget.org/packages/CDK.Datalake.Constructs/
```

## Usage

### Basic

```typescript
import { DataLake } from '@randyridgley/cdk-datalake-constructs';

const taxiPipes: Array<dl.Pipeline> = [
  pipelines.YellowPipeline(),
  pipelines.GreenPipeline(),
]

const dataProducts: Array<dl.DataProduct> = [{
  pipelines: taxiPipes,
  accountId: lakeAccountId,
  dataCatalogAccountId: '123456789012',
  databaseName: 'taxi-product'
}]

// deploy to local account
new dl.DataLake(this, 'LocalDataLake', {
  name: 'data-lake',
  accountId: centralAccountId,
  region: 'us-east-1',
  policyTags: {
    "classification": "public,confidential,highlyconfidential,restricted,critical",
    "owner": "product,central,consumer"
  },
  stageName: Stage.PROD,
  dataProducts: dataProducts,
  createDefaultDatabase: false
});
```

### Data Mesh
You can setup cross account access and pre-created policy tags for TBAC access in Lake Formation

```typescript
const lakeAccountId = app.node.tryGetContext('lakeAccountId')
const centralAccountId = app.node.tryGetContext('centralAccountId')
const consumerAccountId = app.node.tryGetContext('consumerAccountId')

const taxiPipes: Array<dl.Pipeline> = [
  pipelines.YellowPipeline(),
  pipelines.GreenPipeline(),
]

const dataProducts: Array<dl.DataProduct> = [{
  pipelines: taxiPipes,
  accountId: lakeAccountId,
  dataCatalogAccountId: centralAccountId,
  databaseName: 'taxi-product'
}]

// deploy to the central account
new dl.DataLake(this, 'CentralDataLake', {
  name: 'central-lake',
  accountId: centralAccountId,
  region: 'us-east-1',
  policyTags: {
    "classification": "public,confidential,highlyconfidential,restricted,critical",
    "owner": "product,central,consumer"
  },
  stageName: Stage.PROD,
  crossAccount: {
    consumerAccountIds: [consumerAccountId, lakeAccountId],
    dataCatalogOwnerAccountId: centralAccountId,
    region: 'us-east-1', // this is still only single region today    
  },
  dataProducts: dataProducts,
  createDefaultDatabase: true
});

// deploy to the data product account
const datalake = new dl.DataLake(this, 'LocalDataLake', {
  name: 'local-lake',
  accountId: lakeAccountId,
  region: 'us-east-1',
  stageName: Stage.PROD,
  dataProducts: dataProducts,
  createDefaultDatabase: true
});

// Optionally add custom resource to download public data set products
datalake.createDownloaderCustomResource(accountId, region, props.stageName)

// deploy to consumer account
const datalake = new dl.DataLake(this, 'ConsumerDataLake', {
  name: 'consumer-lake',
  accountId: consumerAccountId,
  region: 'us-east-1',
  stageName: Stage.PROD,
  policyTags: {
    "access": "analyst,engineer,marketing"
  },
  createDefaultDatabase: true
});
```
