[Victor Manuel Quiñones Victor]

Hi guys, I need some help here...

I need to serialize some objects and save them into the database. What library would you suggest for it?

Thank you

there are a few options, each with different pros/cons. roughly in
order of personal preference:

JSON:
pro: works in any language, easy to read
con: not the fastest, not the most compact

pickle:
pro: quite fast, easy and very transparent on Python
con: python only

messagepack:
pro: very fast, very compact
con: depends on a not-so-common library

glob:
pro: very fast, very compact
con: go only

protocolbuffers:
pro: quite fast, very compact, multi-version compatibility
con: not widespread, limited language support

tnetstrings:
pro: quite fast, compact, somewhat readable
con: not widespread

yaml:
pro: simple, readable, readable on many languages
con: not compact

XML:
pro: many utilities, many languages
con: no need to enumerate...


in practce, i'd say: if it's absolutely, definitely python only, and
there's some real speed/size concerns, use pickle. for almost
everything else, JSON
