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

Configure and schedule MongoDB metadata workflows from the OpenMetadata UI:

- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)

{% partial file="/v1.1.2/connectors/ingestion-modes-tiles.md" variables={yamlPath: "/connectors/database/mongodb/yaml"} /%}

{% partial file="/v1.1.2/connectors/external-ingestion-deployment.md" /%}

## Requirements

{%inlineCallout icon="description" bold="OpenMetadata 0.12 or later" href="/deployment"%}
To deploy OpenMetadata, check the Deployment guides.
{%/inlineCallout%}

To fetch the metadata from MongoDB to OpenMetadata, the MongoDB user must have access to perform `find` operation on collection and `listCollection` operations on database available in MongoDB.

### Python Requirements

To run the MongoDB ingestion, you will need to install:

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

## Metadata Ingestion

All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/mongoDBConnection.json)
you can find the structure to create a connection to MongoDB.

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](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)

### 1. Define the YAML Config

This is a sample config for MongoDB:

{% codePreview %}

{% codeInfoContainer %}

#### Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

**username**: Username to connect to Mongodb. This user must have access to perform `find` operation on collection and `listCollection` operations on database available in MongoDB.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

**password**: Password to connect to MongoDB.

{% /codeInfo %}

{% codeInfo srNumber=3 %}

**hostPort**: The hostPort parameter specifies the host and port of the MongoDB. This should be specified as a string in the format `hostname:port`. E.g., `localhost:27017`.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

**connectionURI**: MongoDB connection string is a concise string of parameters used to establish a connection between an OpenMetadata and a MongoDB database. For ex. `mongodb://username:password@mongodb0.example.com:27017`.

{% /codeInfo %}

{% codeInfo srNumber=6 %}

**databaseName**: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.

{% /codeInfo %}

#### Source Configuration - Source Config

{% codeInfo srNumber=9 %}

The `sourceConfig` is defined [here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/databaseServiceMetadataPipeline.json):

**markDeletedTables**: To flag tables as soft-deleted if they are not present anymore in the source system.

**includeTables**: true or false, to ingest table data. Default is true.

**includeViews**: true or false, to ingest views definitions.

**databaseFilterPattern**, **schemaFilterPattern**, **tableFilterPattern**: Note that the filter supports regex as include or exclude. You can find examples [here](/connectors/ingestion/workflows/metadata/filter-patterns/database)

{% /codeInfo %}

#### Sink Configuration

{% codeInfo srNumber=10 %}

To send the metadata to OpenMetadata, it needs to be specified as `type: metadata-rest`.

{% /codeInfo %}

{% partial file="/v1.1.2/connectors/workflow-config.md" /%}

#### Advanced Configuration

{% codeInfo srNumber=7 %}

**Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}


{% /codeInfoContainer %}

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

```yaml
source:
  type: mongodb
  serviceName: local_mongodb
  serviceConnection:
    config:
      type: MongoDB
      connectionDetails:
```
```yaml {% srNumber=1 %}
        username: username
```
```yaml {% srNumber=2 %}
        password: password
```
```yaml {% srNumber=3 %}
        hostPort: localhost:27017
```
```yaml {% srNumber=5 %}
        # connectionURI: mongodb://username:password@mongodb0.example.com:27017
```
```yaml {% srNumber=7 %}
        # connectionOptions:
        #   key: value
```
```yaml {% srNumber=6 %}
      database: custom_database_name
```

```yaml {% srNumber=9 %}
  sourceConfig:
    config:
      type: DatabaseMetadata
      markDeletedTables: true
      includeTables: true
      includeViews: true
      # includeTags: true
      # databaseFilterPattern:
      #   includes:
      #     - database1
      #     - database2
      #   excludes:
      #     - database3
      #     - database4
      # schemaFilterPattern:
      #   includes:
      #     - schema1
      #     - schema2
      #   excludes:
      #     - schema3
      #     - schema4
      # tableFilterPattern:
      #   includes:
      #     - users
      #     - type_test
      #   excludes:
      #     - table3
      #     - table4
```

```yaml {% srNumber=10 %}
sink:
  type: metadata-rest
  config: {}
```

{% partial file="/v1.1.2/connectors/workflow-config-yaml.md" /%}

{% /codeBlock %}

{% /codePreview %}

### 2. Run with the CLI

First, we will need to save the YAML file. Afterward, and with all requirements installed, we can run:

```bash
metadata ingest -c <path-to-yaml>
```

Note that from connector to connector, this recipe will always be the same. By updating the YAML configuration,
you will be able to extract metadata from different sources.
