Julian Hyde, on behalf of the Apache Calcite Team Disclaimer: Apache Calcite is an effort undergoing incubation at TheApache Software Foundation (ASF), sponsored by Apache Incubator.Incubation is required of all newly accepted projects until a furtherreview indicates that the infrastructure, communications, and decisionmaking process have stabilized in a manner consistent with othersuccessful ASF projects. While incubation status is not necessarily areflection of the completeness or stability of the code, it doesindicate that the project has yet to be fully endorsed by the ASF.
