Hi fellas, If its not too much of a hassle, i have a few questions regarding parallelism & the internal algorithms 1. What is the difference between Data-Flow, and Mitosis? 2. Is there a special reason why the distinct count aggregation is not parallelized just like the other aggregation functions? Is it just a matter of not making it into the release, or is there a fundamental problem here. Note: even though the parallel distinct can be slower in certain distributions, it could still be useful... 3. Are there any plans on supporting parallel frameworks like OpenMP/Intel TBB directly within the low-level MAL functions? Providing data-parallelism on the loop-code level could even increase performance. Or did you already play with it and decided that the performance gain is just not worth it? 4. Is there a way for me to prevent MonetDB server from cleaning up all intermediate BATs between server restarts. I've read here that some intermediates (like join indices etc.) are lost between restarts... is it still correct? Thank you very much for your time, Keep up the amazing job of building the most powerful columnar database out there! -- View this message in context: http://old.nabble.com/Some-questions-regarding-parallelism-and-other-stuff.....
