Druid is a next-gen open source alternative to analytical databases such as Vertica, Greenplum, and Exadata, and data warehouses such as Snowflake, BigQuery, and Redshift. ### Getting started You can get started with Druid with our [quickstart](https://druid.apache.org/docs/latest/tutorials/quickstart.html). 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 console](https://druid.apache.org/docs/latest/operations/druid-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, [segments](https://druid.apache.org/docs/latest/design/segments.html), [ingestion tasks](https://druid.apache.org/docs/latest/ingestion/tasks.html), and [servers]() 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 You can find the [documentation for the latest Druid release](https://druid.apache.org/docs/latest/) on the [project website](https://druid.apache.org). If you would like to contribute documentation, please do so under `/docs` in this repository and submit a pull request. ### Community Community support is available on the [druid-user mailing list](https://groups.google.com/forum/#!forum/druid-user), which is hosted at Google Groups. Development discussions occur on [dev@druid.apache.org](https://lists.apache.org/list.html?dev@druid.apache.org), which you can subscribe to by emailing [dev-subscribe@druid.apache.org](mailto:dev-subscribe@druid.apache.org). Chat with Druid committers and users in real-time on the `#druid` channel in the Apache Slack team. Please use [this invitation link to join the ASF Slack](https://s.apache.org/slack-invite), and once joined, go into the `#druid` channel. ### Building from source Please note that JDK 8 is required to build Druid. For instructions on building Druid from source, see [docs/development/build.md](docs/development/build.md) ### Contributing Please follow the [community guidelines](https://druid.apache.org/community/) for contributing. ### License [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0) *Disclaimer: Apache Druid is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.*
