A new Data Dictionary based on transactional tables is being developed for the MySQL server. That project is a huge step forward improving many aspects of the server. The new Data Dictionary provides API which is intended to be used by all the participants of the MySQL Server Ecosystem. The slides make a brief introduction about what general Data Dictionary is, provide overview of the MySQL traditional Data Dictionary and its limitations. Then, the presentation shows the design goals of the new Data Dictionary and sketch the main architectural decisions. It also provides the description of a few visible advantages for the MySQL users.
These are the slides for my session on OOW 2014.
