Druid excels as a data warehousing solution for fast aggregate queries on petabyte sized data sets. Druid supports a variety of flexible filters, exact calculations, approximate algorithms, and other useful calculations. Druid can load both streaming and batch data and integrates with Samza, Kafka, Storm, and Hadoop. ### License [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0) ### More Information More information about Druid can be found on . ### Documentation You can find the [latest Druid Documentation](http://druid.io/docs/latest/) on the [project website](http://druid.io/docs/latest/).
