# Oracle

For context on getting started with ingestion, check out our [metadata ingestion guide](../README.md).

## Setup

To install this plugin, run `pip install 'acryl-datahub[oracle]'`.

## Capabilities

This plugin extracts the following:

- Metadata for databases, schemas, and tables
- Column types associated with each table
- Table, row, and column statistics via optional [SQL profiling](./sql_profiles.md)

Using the Oracle source requires that you've also installed the correct drivers; see the [cx_Oracle docs](https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html). The easiest one is the [Oracle Instant Client](https://www.oracle.com/database/technologies/instant-client.html).

## Quickstart 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](../README.md#recipes).

```yml
source:
  type: oracle
  config:
    # Coordinates
    host_port: localhost:5432
    database: dbname

    # Credentials
    username: user
    password: pass

    # Options
    service_name: svc # omit database if using this option

sink:
  # sink configs
```

## Config details

Note that a `.` is used to denote nested fields in the YAML recipe.

Exactly one of `database` or `service_name` is required.

As a SQL-based service, the Athena integration is also supported by our SQL profiler. See [here](./sql_profiles.md) for more details on configuration.
