Subject Re: IEP-19: Optimize SQL indexes
Date Thu, 26 Apr 2018 13:09:42 GMT
It is impossible to estimate what is more critical because it would require
prototypes for every idea to estimate the impact. Instead, we should start
working on the simplest things, such as IGINTE-8386 [1] or IGNITE-8384 [2].
And then gradually swtich to more and more complex changes.
