The command for creating a column family is

create column family ColumnFamilyName with comparator = ‘Type’ and column_metadata = [ {column_name: Col-umnName, validation_class: ‘Type’, index_type: KEYS }, …];

Note: When referring to types, look at the types table and add them without the single quotes. As mentioned before, the column_metadata is optional.

For the BookCo sales, we should create a ‘sale’ standard column family by using the UTF8Type and then again this type for validation class, without indexing any key at the moment.
