Use a Cassandra map column - the keys of the map can be arbitrary. But if there are some standard set of columns that are always or commonly present, make them explicit Cassandra columns. And if the avro values have different types, you may want to have several Cassandra map columns, one for each value type you need to distinguish on queries. In some cases you might want to use user defined types (UDT.)
