You're heading in the right direction. Id suggest not using writables, and using a flexible system like thrift or protobuf. They support expandability without invalidating old data.
But you want to be careful about putting too much code in a filter. It gets called frequently and I'm not exactly sure of the perf trade offs yet. Be prepared to be surprised I guess?

Would I also need to write ColumnValueFilters to do scans of rows with a collection containing a value? This is my first attempt at a many2one in a singe row. Many thanks, Tim
