Hello all,
Is there anything to implementing multi range read for storage engines? Or is there a default implementation that is likely good enough.
Also, is there anything one can read to understand how the feature works and its benefits?
Thanks -Zardosht
Hi Zardosht, I googled "MySQL Multi Range Read" and got among other references: 1. https://kb.askmonty.org/en/multi-range-read-optimization/ 2. http://dev.mysql.com/doc/refman/5.6/en/mrr-optimization.html The first article was written by Sergey Petrunia, the guy who wrote disk-sweep MRR. I find it the most comprehensive. The second article was written also by him but when he worked at Sun. Later this article was slightly changed by MySQL/Oracle people. Regards, Igor.
