# Other SQLAlchemy databases
|
|
|
|
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[sqlalchemy]'`.
|
|
|
|
The `sqlalchemy` source is useful if we don't have a pre-built source for your chosen
|
|
database system, but there is an [SQLAlchemy dialect](https://docs.sqlalchemy.org/en/14/dialects/)
|
|
defined elsewhere. In order to use this, you must `pip install` the required dialect packages yourself.
|
|
|
|
## Capabilities
|
|
|
|
This plugin extracts the following:
|
|
|
|
- Metadata for databases, schemas, views, and tables
|
|
- Column types associated with each table
|
|
- Table, row, and column statistics via optional [SQL profiling](./sql_profiles.md)
|
|

## 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: sqlalchemy
|
|
config:
|
|
# Coordinates
|
|
connect_uri: "dialect+driver://username:password@host:port/database"
|
|
|
|
sink:
|
|
# sink configs
|
|
```
|
|
|
|
## Config details
|
|
|
|
Note that a `.` is used to denote nested fields in the YAML recipe.
|
|
|
|
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.
