Release Note:

Hide
Pass the -D flag generator.multiple.columnfamilies on the command-line if you want the generator to write three column families rather than the default one. When set, we will write the usual 'meta' column family and use it checking linked-list is wholesome but we will also write a 'tiny' column family and a 'big' column family to provoke uneven flushing; good for testing the flush-by-columnfamily feature.

Let me work on this. It would be excellent if we could have confidence to turn this on earlier rather than later.
