I've been doing some reading about the Antelope and Barracuda file formats for InnoDB. I recall at least one source mentioning that the two should not be used simultaneously.
I can't think of a good reason (while using innodb_file_per_table) that I couldn't use Antelope on one table and Barracuda on another. However, maybe I'm missing something.
Are there any good reasons to avoid using Antelope and Barracuda simultaneously?
(Note: The reason I'm planning on using both simultaneously is that I don't want to mess with our existing (quite large) tables. Perhaps this isn't a big deal? Is migrating from Antelope to Barracuda trivial, even for large tables?)
