In this section, we provide guides and references to use the S3 Datalake connector.

Configure and schedule S3 Datalake metadata and profiler workflows from the OpenMetadata UI:
- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)
- [dbt Integration](#dbt-integration)

## Requirements

**Note:** S3 Datalake connector supports extracting metadata from file types `JSON`, `CSV`, `TSV` & `Parquet`.


### S3 Permissions

To execute metadata extraction AWS account should have enough access to fetch required data. The <strong>Bucket Policy</strong> in AWS requires at least these permissions:

```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::<my bucket>",
                "arn:aws:s3:::<my bucket>/*"
            ]
        }
    ]
}
```

### Python Requirements

{% partial file="/v1.6/connectors/python-requirements.md" /%}

If running OpenMetadata version greater than 0.13, you will need to install the Datalake ingestion for S3:

#### S3 installation

```bash
pip3 install "openmetadata-ingestion[datalake-s3]"
```


#### If version <0.13

You will be installing the requirements for S3

```bash
pip3 install "openmetadata-ingestion[datalake]"
```

## Metadata Ingestion
All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to Datalake.

In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following JSON Schema.

## 1. Define the YAML Config

#### Source Configuration - Source Config using AWS S3

### This is a sample config for Datalake using AWS S3:

{% codePreview %}

{% codeInfoContainer %}

#### Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

* **awsAccessKeyId**: Enter your secure access key ID for your DynamoDB connection. The specified key ID should be authorized to read all databases you want to include in the metadata ingestion workflow.
* **awsSecretAccessKey**: Enter the Secret Access Key (the passcode key pair to the key ID from above).
* **awsRegion**: Specify the region in which your DynamoDB is located. This setting is required even if you have configured a local AWS profile.
* **schemaFilterPattern** and **tableFilterPattern**: Note that the `schemaFilterPattern` and `tableFilterPattern` both support regex as `include` or `exclude`. E.g.,

{% /codeInfo %}

{% partial file="/v1.6/connectors/yaml/ingestion-sink-def.md" /%}

{% partial file="/v1.6/connectors/yaml/workflow-config-def.md" /%}

{% /codeInfoContainer %}

{% codeBlock fileName="filename.yaml" %}

```yaml {% isCodeBlock=true %}
source:
  type: datalake
  serviceName: local_datalake
  serviceConnection:
    config:
      type: Datalake
```

```yaml {% srNumber=1 %}
      configSource:      
        securityConfig: 
          awsAccessKeyId: aws access key id
          awsSecretAccessKey: aws secret access key
          awsRegion: aws region
      bucketName: bucket name
      prefix: prefix
```
