Druid is a distributed, column-oriented, real-time analytics data store
that is commonly used to power exploratory dashboards in multi-tenant
environments.
Apache Druid (incubating) is a high performance analytics data store for event-driven data.
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, Spark, and Hadoop.
*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.*
