Description

icDuplicateByte	Indicates that the compression is duplicate-byte compression. Duplicate-byte compression works by removing all duplicate bytes from adjacent index keys in an index.
icFull	Indicates that the compression is both duplicate-byte and trailing-byte compression (or full compression).
icNone	Indicates that there is no compression.
icTrailingByte	Indicates that the compression is trailing-byte compression. Trailing-byte compression works by removing all trailing spaces and NULLs from the index keys in an index, and is most useful with string fields.
