i will put this in discussion list, sorry wrong mail list for this topic 2013/7/10 Roberto Spadim <roberto@spadim.com.br>
well, another doubts that i had some time ago reading unireg source...
1)why it have a 64k limit? that's a logical limit (a limit in int variable or char or something like it)? or just a "well i think 64k is a good 'constant' limit"?
2)why we "still" with this "old" unireg format? i know that someone must start the new format and it will not be compatible with mysql... but there's any raw idea or a issue in mdev or lauchpad about changing .frm format or creating a new one?
maybe something more human readable YAML or JSON, and a space for engine information https://mariadb.atlassian.net/browse/MDEV-3936
