Subject Purpose of BLOB datatype
Date Mon, 08 Jul 2013 09:07:56 GMT
Hi all,

I am curious why there is BLOB datatype that accepts HEX strings only.

HEX encoding requires twice as much space as original data, thus it is
rather ineffective. Instead, base64 encoding with ASCII datatype seems more
effective in terms of space, and I believe it doesn't impose noticeable
performance penalty either.

So, are there any special use cases for BLOBs, or should I give up on them
and use ASCII + base64 for my binaries?

Thanks in advance,
Pavel.
