Turnilo is a business intelligence, data exploration and visualization web application for [Apache Druid](https://druid.apache.org).
Turnilo is a fork of [Pivot](https://github.com/implydata/pivot) which is currently available under commercial licence only.
This repository was forked from the stalled repository [Swiv](https://github.com/yahoo/swiv)
with the latest version of Pivot under Apache license.

## Motivation

[Druid](https://github.com/druid-io/druid) is heavily used as business intelligence platform at [Allegro](https://allegro.tech/).
In order to gain wide adoption of non-technical users, Druid requires simple yet powerful user interface.
In Allegro we have decided that we are going to continue Pivot development as an open source software,
this is how Turnilo emerged.

## Manifesto

* High usability for non-technical users over sophisticated but rarely used features.
* Focus on interactive data exploration over static predefined dashboards.
* Self-describing reports for users without deep domain expertise.
* Outstanding integration with Druid over support for other data sources like SQL databases.
* Focus on data visualizations over Druid cluster or data ingestion management.
* Data cubes configuration as a code over UI editor backed by non-versioned database.
* Stateless over stateful server-side architecture.
* Support for most recent versions of standards compliant browsers.

## Features

* Intuitive, drag and drop, gorgeous user interface to visualize Druid datasets.
* Fully dedicated to low latency Druid
[Timeseries](https://druid.apache.org/docs/latest/querying/timeseriesquery.html),
[TopN](https://druid.apache.org/docs/latest/querying/topnquery.html) and
[GroupBy](https://druid.apache.org/docs/latest/querying/groupbyquery.html) queries.
* Unified view for historical and real-time data.
* Blazingly fast.

## Join us

Feel free to ask on [GitHub Discussions](https://github.com/allegro/turnilo/discussions)
or join the chat on [Slack](https://join.slack.com/t/turnilo/shared_invite/enQtOTI4ODcxMjcyNjU2LTFlOTk5YWZlOGMyZDZhZWU3MGNjNDRhZmI1Y2UzNDlkZmY3YzYxYTJhYzIzMzc0MTc3MzA3OTE1NmQ5NDI1M2I).

## Pre-requisites

* [Node.js](https://nodejs.org/) - 14.x or 16.x version

:warning:
Do not use `yarn` command for dependency management and project build, use `npm` instead.
With `npm` builds are reproducible (thanks to package-lock.json) and even faster than with `yarn`.

## Usage

Install Turnilo distribution using [npm](https://www.npmjs.com/).

```
npm install -g turnilo
```

Start off by running Turnilo with example datasets
and open [http://localhost:9090/](http://localhost:9090/).

```
turnilo run-examples
```

Use `connect-druid` command to connect to the existing Druid broker.
Turnilo will automatically introspect your Druid broker and figure out available datasets.

```
turnilo connect-druid http[s]://druid-broker-hostname[:port]
```

### End to end tests

Run all e2e tests. It will start Turnilo with example datasets in background.

```
npm run e2e
```

### End to end tests development

Run server

```
npm start:dev:examples
```

Run cypress interactive tools for e2e testing

```
npm run e2e:dev
