| Subj: || || Reconfiguration and Database Space |

We are preparing for a database Reconfiguration where additional nodes, amps, and clusters will be added. In researching preparation
activities, I cannot find any mention that individual databases must have a certain percentage of freespace (maxperm minus currentperm) to prevent
the redistribution process from failing due to "insufficient database space" on amps with skewed data (similar to what can happen when restoring
into a larger system with more amps).
Am I to assume that Reconfiguration will handle this by automatically altering the maxperm amounts of the various databases as needed? (I am
aware that a certain amount of freespace is needed on the total system for fallback rows, especially when changing clusters without adding amps,
but this is not the case here.) Your help in understanding this will be appreciated.
