Druid's main value add is to reduce time to insight and action. Druid is designed for workflows where fast queries and ingest really matter. Druid excels at powering UIs, running operational (ad-hoc) queries, or handling high concurrency. Consider Druid as an open source alternative to data warehouses for a variety of use cases. The [design documentation](https://druid.apache.org/docs/latest/design/architecture.html) explains the key concepts. ### Getting started You can get started with Druid with our [local](https://druid.apache.org/docs/latest/tutorials/quickstart.html) or [Docker](http://druid.apache.org/docs/latest/tutorials/docker.html) quickstart. For Kubernetes deployments, the [druid-operator](https://github.com/apache/druid-operator) is maintained in a separate repository. Druid provides a rich set of APIs (via HTTP and [JDBC](https://druid.apache.org/docs/latest/querying/sql.html#jdbc)) for loading, managing, and querying your data. You can also interact with Druid via the built-in [web console](https://druid.apache.org/docs/latest/operations/web-console.html) (shown below). #### Load data [](https://druid.apache.org/docs/latest/ingestion/index.html) Load [streaming](https://druid.apache.org/docs/latest/ingestion/index.html#streaming) and [batch](https://druid.apache.org/docs/latest/ingestion/index.html#batch) data using a point-and-click wizard to guide you through ingestion setup. Monitor one off tasks and ingestion supervisors. #### Manage the cluster [](https://druid.apache.org/docs/latest/ingestion/data-management.html) Manage your cluster with ease. Get a view of your [datasources](https://druid.apache.org/docs/latest/design/architecture.html), [segments](https://druid.apache.org/docs/latest/design/segments.html), [ingestion tasks](https://druid.apache.org/docs/latest/ingestion/tasks.html), and [services](https://druid.apache.org/docs/latest/design/processes.html) from one convenient location. All powered by [SQL systems tables](https://druid.apache.org/docs/latest/querying/sql.html#metadata-tables), allowing you to see the underlying query for each view. #### Issue queries [](https://druid.apache.org/docs/latest/querying/sql.html) Use the built-in query workbench to prototype [DruidSQL](https://druid.apache.org/docs/latest/querying/sql.html) and [native](https://druid.apache.org/docs/latest/querying/querying.html) queries or connect one of the [many tools](https://druid.apache.org/libraries.html) that help you make the most out of Druid. ### Documentation See the [latest documentation](https://druid.apache.org/docs/latest/) for the documentation for the current official release. If you need information on a previous release, you can browse [previous releases documentation](https://druid.apache.org/docs/). Make documentation and tutorials updates in [`/docs`](https://github.com/apache/druid/tree/master/docs) using [Markdown](https://www.markdownguide.org/) or extended Markdown [(MDX)](https://mdxjs.com/). Then, open a pull request. To build the site locally, you need Node 18 or higher and to install Docusaurus 3 with `npm|yarn install` in the `website` directory. Then you can run `npm|yarn start` to launch a local build of the docs. If you're looking to update non-doc pages like Use Cases, those files are in the [`druid-website-src`](https://github.com/apache/druid-website-src/tree/master) repo. For more information, see the [README in the `./website` directory](./website/README.md). ### Community Visit the official project [community](https://druid.apache.org/community/) page to read about getting involved in contributing to Apache Druid, and how we help one another use and operate Druid. * Druid users can find help in the [`druid-user`](https://groups.google.com/forum/#!forum/druid-user) mailing list on Google Groups, and have more technical conversations in `#troubleshooting` on Slack. * Druid development discussions take place in the [`druid-dev`](https://lists.apache.org/list.html?dev@druid.apache.org) mailing list ([dev@druid.apache.org](https://lists.apache.org/list.html?dev@druid.apache.org)).
