Hi Jan, Thank you for your answer.
I am writing to the TokuDB community. I hope for good news ☺ Cordialement, [Claranet]<http://www.claranet.fr/> [Linkedin]<http://www.linkedin.com/company/claranet> [Twitter]<https://twitter.com/#!/Claranet_FR> [Youtube]<http://www.youtube.com/user/ClaranetFR> [Gartner MQ]<http://www.claranet.fr/propos-de/gartner.html> De : Jan Lindström [mailto:jan.lindst...@mariadb.com] Envoyé : mardi 30 septembre 2014 10:38 À : Christophe Le Roux; Maria Discuss Objet : Re: [Maria-discuss] MariaDB,TokuDB and FusionIO Hi, On Tue, Sep 30, 2014 at 11:27 AM, Christophe Le Roux <christophe.le.r...@fr.clara.net<mailto:christophe.le.r...@fr.clara.net>> wrote: About NVM compression, is it a hardware compression doing by the FusionIO controller or is it a software compression doing by the CPU of the server ? Compression is done by CPU in the MariaDB server (InnoDB/XtraDB storage engine). About Atomic Write, I understand there is missing code to have this feature to the TokuDB engine. Should I ask to the Mariadb dev team or the Tokutek dev team (or SanDisk/FusionIO dev team ?) to add it (maybe it’s technically no doable ?)? I would start from Tokutek dev team, I do not know fully how database tables are stored on Tokutek, but I do not see immediately a reason why atomic writes would not be possible. Do you think this can boost performances for huge TokuDB tables ? Atomic will boost performance but only if database is stored on device that supports atomic writes. R: Jan
