Description

Problem:

• Currently undefined class is placed in the org.apache.geode.cache.query.internal package
• But undefined is exposed to the user when queries try to do something like projecting a field that does not exist or extract a value from NULL

Expectation

• Anything that is exposed to the user should not be in the internal package.
• This needs to be moved to public package

Issues

• Doing this may result in breaking backwards compatibility
• Older clients will be expecting undefined from an internal package but will receive a undefined present in a package that it is not able to identify.

 

This task will need a discussion to find a viable solution.
