Hi all,
This week's blog entry would get delayed by couple of days. I have started coding though and would like to give heads up on what I'm doing.
I've looked at the diffs for "Cost model project" of mysql: http://bazaar.launchpad.net/~mysql/mysql-server/5.7/revision/7596 and http://bazaar.launchpad.net/~mysql/mysql-server/5.7/revision/7222 . These give a pretty good idea about what are the hard-coded constants and where are they being used.
The idea is to multiply "READ_TIME_FACTOR" and "SCAN_TIME_FACTOR" to the values returned by read_time() and scan_time() in handler.h, while returning. These values would be read from a table in mysql db. For that I've looked at sql_statistics.cc. After completing this, I'll first change the values of these constants manually and check if the better or worse query plans are being selected. I'll first do the last step manually, to check if everything is working as expected and later automate it.
Regards Anshu

Hi all,
Sorry for the irregular updates. I had been busy for last couple of days and might still be busy for 1-2 days more. I would be completely free starting next week, and would be updating my blog weekly on every Monday (so 1st update would be on May 12). I would also send the link of my

weekly on the mailing list.
As discussed on irc, I started to explore the pair of constants: handler::scan_time() and handler::read_time().
