# 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.
