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.
