   * ~-'''BLOOMFILTER''' specifies which bloom filter to use for the column family. By default,
none of the bloom filters is used. You can specify the options in two ways: with '''VECTOR_SIZE'''
and '''NUM_HASH''', or with '''NUM_ENTRIES'''. '''VECTOR_SIZE''' specifies the number of elements
in the vector, and '''NUM_HASH''' specifies the number of hash functions to use; With '''NUM_ENTRIES''',
you  specify only the approximated number of entries in the column, and '''VECTOR_SIZE'''
and '''NUM_HASH''' are automatically determined.-~
