Hi I am Arlene Flavie a software Engineering student and I wish to make my contribution to opensource through Mariadb. I have build mariadb from a git clone and ran the tests. I am interested in working on adding routines to import and export popular data formats to and from dynamic columns. I am currently studying the dynamic column data structures in mysql/ma_dyncol.** and I think what Oleksandr Byeklin proposed makes sense to me. Thats using methods like xxx_init() and xxx_named() to play with the old dynamic column blob format. I will be applying to work on this task for Gsoc 2015 and im hoping to learn much in open source development. Cheers.
