But more critically I noticed you referred to altering the names of columns to suit NDB. How will this be accomplished? Changing a column name in an openstack application is no longer trivial, because online upgrades must be supported for applications like Nova and Neutron. A column name can't just change to a new name, both columns have to exist and logic must be added to keep these columns synchronized.
correction, the phrase was "Row character length limits 65k -> 14k" - does this refer to the total size of a row? I guess rows that store JSON or tables like keystone tokens are what you had in mind here, can you give specifics ?
