Hi!
I'm gathering 5.6 options that are not present in 10.0 and the way we want to handle them. Could you check options listed below and if you're aware of their destiny indicate if options: * not used or needed in MariaDB * to be implemented in later 10.x versions * tuned via different 10.x specific options
The following options exist in 5.6 but not in 10.0: * end-markers-in-json * optimizer-trace * optimizer-trace-features * optimizer-trace-offset * optimizer-trace-limit * optimizer-trace-max-mem-sizea These all are for Optimizer Trace. It hasn't been ported to 10.0. There is no consensus among MariaDB optimizer developers the whether optimizer trace is useful and whether it should be ported.
* eq-range-index-dive-limit
This is from a feature that hasn't been ported from 5.6 to 10.0. In my opinion, we should port it (and maybe think how it can work with EITS). I don't know what others think, though. BR Sergei -- Sergei Petrunia, Software Developer MariaDB | Skype: sergefp | Blog: http://s.petrunia.net/blog
