Framework Architecture

[Ron Wheeler]

If there is an interest in redoing the framework or upgrading it or
changing the base technology and the application interface, perhaps this
is something that should be investigated to see if it simplifies the
process and adds an optimization layer that we don't have to write.

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.
