# Pulsar

## Overview

Pulsar is a streaming or integration platform. Learn more in the [official Pulsar documentation](https://pulsar.apache.org/).

The DataHub integration for Pulsar covers streaming/integration entities such as topics, connectors, pipelines, or jobs. It also captures stateful deletion detection.

### Important Capabilities
| Capability | Status | Notes |
| ---------- | ------ | ----- |
| [Detect Deleted Entities](../../../../metadata-ingestion/docs/dev_guides/stateful.md#stale-entity-removal) | ✅ | Enabled by default via stateful ingestion. |
| [Domains](../../../domains.md) | ✅ | Supported via the `domain` config field. |
| [Platform Instance](../../../platform-instances.md) | ✅ | Enabled by default. |
| Schema Metadata | ✅ | Enabled by default. |

### Overview

The `pulsar` module ingests metadata from Pulsar into DataHub. It is intended for production ingestion workflows and module-specific capabilities are documented below.

The Datahub Pulsar source plugin extracts `topic` and `schema` metadata from an Apache Pulsar instance and ingest the information into Datahub. The plugin uses the [Pulsar admin Rest API interface](https://pulsar.apache.org/admin-rest-api/#) to interact with the Pulsar instance. The following APIs are used in order to:

- [Get the list of existing tenants](https://pulsar.apache.org/admin-rest-api/#tag/tenants)
- [Get the list of namespaces associated with each tenant](https://pulsar.apache.org/admin-rest-api/#tag/namespaces)
- [Get the list of topics associated with each namespace](https://pulsar.apache.org/admin-rest-api/#tag/persistent-topic)
  - persistent topics
  - persistent partitioned topics
  - non-persistent topics
  - non-persistent partitioned topics
- [Get the latest schema associated with each topic](https://pulsar.apache.org/admin-rest-api/#tag/schemas)

The data is extracted on `tenant` and `namespace` basis, topics with corresponding schema (if available) are ingested as [Dataset](docs/generated/metamodel/entities/dataset.md) into Datahub. Some additional values like `schema description`, `schema_version`, `schema_type` and `partitioned` are included as `DatasetProperties`.

### Prerequisites

- **Pulsar Instance**: Access with valid access token (if authentication enabled)
- **Version**: Pulsar 2.7.0 or later
- **Role**: `superUser` required to list all tenants

:::info
A `superUser` role is required for listing all existing tenants within a Pulsar instance.
:::


### Install the Plugin
```shell
pip install 'acryl-datahub[pulsar]'
```

### Starter Recipe
Check out the following recipe to get started with ingestion! See [below](#config-details) for full configuration options.


For general pointers on writing and running a recipe, see our [main recipe guide](../../../../metadata-ingestion/README.md#recipes).
```yaml
source:
  type: "pulsar"
  config:
    env: "TEST"
    platform_instance: "local"
    ## Pulsar client connection config ##
    web_service_url: "https://localhost:8443"
    verify_ssl: "/opt/certs/ca.cert.pem"
    # Issuer url for auth document, for example "http://localhost:8083/realms/pulsar"
    issuer_url: <issuer_url>
    client_id: ${CLIENT_ID}
    client_secret: ${CLIENT_SECRET}
    # Tenant list to scrape
    tenants:
      - tenant_1
      - tenant_2
    # Topic filter pattern
    topic_patterns:
      allow:
        - ".*sales.*"

sink:
# sink configs

```

### Capabilities

Use the **Important Capabilities** table above as the source of truth for supported features and whether additional configuration is required.

:::warning
Always use TLS encryption in a production environment and use variable substitution for sensitive information (e.g. ${CLIENT_ID} and ${CLIENT_SECRET}).
:::

### Limitations

Module behavior is constrained by source APIs, permissions, and metadata exposed by the platform. Refer to capability notes for unsupported or conditional features.

### Troubleshooting

If ingestion fails, validate credentials, permissions, connectivity, and scope filters first. Then review ingestion logs for source-specific errors and adjust configuration accordingly.
