Turnilo

Turnilo is a business intelligence, data exploration and visualization web application for Apache Druid. Turnilo is a fork of Pivot which is currently available under commercial licence only. This repository was forked from the stalled repository Swiv with the latest version of Pivot under Apache license.

Motivation

Druid is heavily used as business intelligence platform at Allegro. 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, TopN and GroupBy queries.
• Unified view for historical and real-time data.
• Blazingly fast.

Pre-requisites

• Node.js - 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.

npm install -g turnilo

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