# Grafana Arrow-DataFusion Data Source
This is the result of an experiment that uses [arrow-datafusion](https://github.com/apache/arrow-datafusion) as a datasource.
You will need the following dependencies installed:
* Docker
* node v14
* yarn
To install the rest of the dependencies, you can run:
```
make setup
```
Start grafana:
```
make start
```
## Example
You can find an example of implementing a datasource [here](crates/datafusion-test-datasource/pkg/github/releases.rs).
Example `releases` query:
```sql
SELECT
date_trunc('week', published_at) AS week,
count(name) AS release_count
FROM
datasource.github.releases
WHERE
owner = 'grafana'
AND repo = 'tempo'
GROUP BY week
ORDER BY week ASC
```
Example `pull_requests` query:
```sql
SELECT
date_trunc('week', created_at) AS week,
count(*) AS pr_count
FROM
datasource.github.pull_requests
WHERE
owner = 'grafana'
AND repo = 'tempo'
GROUP BY week
ORDER BY week ASC
```
