Column name should be bytes, which is converted from data types which are
defined by CompareWith:
Look at the storage-conf.xml file:
~ BytesType: Simple sort by byte value. No validation is performed.
~ AsciiType: Like BytesType, but validates that the input can be
~ parsed as US-ASCII.
~ UTF8Type: A string encoded as UTF8
~ LongType: A 64bit long
~ LexicalUUIDType: A 128bit UUID, compared lexically (by byte value)
~ TimeUUIDType: a 128bit version 1 UUID, compared by timestamp
The value should matching.

This ByteArray can give you something about converting.

Then what kink of column name should I use?

CompareWith defines type for column name/ super column name, and at the
moment, key should be always String.

Subject: long type
I set the "CompareWith" property to "longtype", but I can not insert data.
It seems that something is wrong with the key. If I use longtype comparison,
what key I should use? int?long?
By the way, the language I use is python.
