Support additional single-byte encodings for column-organized tables
The latest updates to DB2 have added the support of codepage 809 (ISO8859-1) for databases using column-organized tables. . This is good for many Western customers, who are able to avoid switching to Unicode (and paying the penalty of 2x or 3x character string sizes). . This is still not so good for other (mostly, Cyrillic) customers, who can use either UTF-8 with CHAR/VARCHAR (3x string sizes) or UTF-16 with GRAPHIC/VARGRAPHIC (2x string sizes). . 2x or 3x character data size mostly kills all the benefits of BLU compression, on many databases. . It would really help if codepages 915 (ISO8859-5) and 1251 (windows-1251) were also supported by column-organized tables - in fact, that would be enough not just for Russia, but also for many other countries using Cyrillic characters.
