In the backup glossary we asked if anyone knew how to get logical data out of physical InnoDB files. Mike Hamrick of Blue Gecko wrote in to say that Percona's InnoDB recovery tool helps to do just that. He writes:
"The 'page_parser' tool will read ibdata files or individual .ibd files and turn them into a series of 16k page files suitable for processing with a tool called 'constraints_parser' which spits out a number of tab separated lines of table data suitable for a LOAD DATA INFILE.
Special thanks to Tim Callaghan for giving a fantastic presentation of VoltDB at Monday's Boston MySQL User Group meeting. Even though the title was "for SQL developers" there was a lot of content for DBAs as well (how backups are done, what the data and server-level architecture is, etc). It was an EXCELLENT presentation on how VoltDB works, and what applications it is and is not appropriate for. The video is almost 2 hours long; there's a LOT of excellent information in it.
