Mark Grover commented on HIVE-2693:
-----------------------------------
Thanks for contributing, [~hagleitn]! I am just about to take a closer look at
your latest patch but like we discussed offline, a better packed byte (with
radix 256) might be a better solution to a digit (i.e. a radix 10) based
serialization. Since we would need a sentinel character for terminating this
arbitrary long sequence of bytes (regardless of what radix we use), we have 2
options:
A. To use a smaller radix and reserve a particular byte as a terminator
B. To use a larger radix (like 256) and have certain escape character to escape
in the terminator if it appears in the content, similar to what we have for
string.
I would prefer the latter (option B). Any particular concerns from anybody
about that?
