Re: Question on the number of column families
One way to model the data would be to use a composite key that is made
up of the RDMS primary_key + "." + field_name. Then just have a single
column that contains the value of the field.
Individual field lookups will be a simple get and to get all of fields
of a record, you would do a scan with startrow => primary_key + ".!",
endrow => primary_key + ".~"
