## Overview

This AWS Solutions Construct implements an Amazon Kinesis Firehose delivery stream connected to an Amazon S3 bucket, and an Amazon Kinesis Analytics application.

Here is a minimal deployable pattern definition:

Typescript

```python
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { KinesisFirehoseToAnalyticsAndS3 } from '@aws-solutions-constructs/aws-kinesisfirehose-s3-and-kinesisanalytics';

new KinesisFirehoseToAnalyticsAndS3(this, 'FirehoseToS3AndAnalyticsPattern', {
  kinesisAnalyticsProps: {
    inputs: [{
      inputSchema: {
        recordColumns: [{
          name: 'ticker_symbol',
          sqlType: 'VARCHAR(4)',
          mapping: '$.ticker_symbol'
        }, {
          name: 'sector',
          sqlType: 'VARCHAR(16)',
          mapping: '$.sector'
        }, {
          name: 'change',
          sqlType: 'REAL',
          mapping: '$.change'
        }, {
          name: 'price',
          sqlType: 'REAL',
          mapping: '$.price'
        }],
        recordFormat: {
          recordFormatType: 'JSON'
        },
        recordEncoding: 'UTF-8'
      },
      namePrefix: 'SOURCE_SQL_STREAM'
    }]
  }
});
```

## Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

### Amazon Kinesis Firehose

* Enable CloudWatch logging for Kinesis Firehose
* Configure least privilege access IAM role for Amazon Kinesis Firehose

### Amazon S3 Bucket

* Configure Access logging for S3 Bucket
* Enable server-side encryption for S3 Bucket using AWS managed KMS Key
* Enforce encryption of data in transit
* Turn on the versioning for S3 Bucket
* Don't allow public access for S3 Bucket
* Retain the S3 Bucket when deleting the CloudFormation stack
* Applies Lifecycle rule to move noncurrent object versions to Glacier storage after 90 days

### Amazon Kinesis Data Analytics

* Configure least privilege access IAM role for Amazon Kinesis Analytics
