Hi Guys, what's the state of "alternative" engines (aria and rocks). AFAIR there were some plans to make aria much more advanced than myisam, transactional (transaction safe?) and more optimized for todays hardware.   What's the status of RocksBD, basically on the mariadb website i can't find recent updates and most of sources on the internet are outdated. Is it 100% compatible with mariadb nowdays, is there a possibility to have "one-file-per-table" (one set of files) or at least per-database? If everything resides in shared space is there a possibility that one write error (eg. resulting from power loss) can make all rocks tables unreadable? Is it possible to efficiently drop eg. 100GB table partition if the table is using rocks?   Last time i checked there were some issues with compaction for Rocks (some limit on DB size, which was rather small can't recall this currently). Is that resolved, and how much additional space is required to compact eg. 1tb database?  How's the adoption and developement of both engines going? Are people using it instead of myisam/toku/inno? Is there a lot of effor put into making aria/rocks better? As i'll have to update many servers in the future what's generally the preferred way to go? Drop everything and just use innodb like Oracle did or move towards rocks/aria for everything which doesn't play with innodb well?   Another interesting topic is that myisam is having performance issues because of spectre/meltdown mitigations and it seems to hit this engine the most (at least in 10.3, 10.4 as far as I recall). Are there some plans to optimize it for new CPUs (maybe it was already done) or all the effors are going into different storage engines and i should abandon myisam long term?  Thanks
