Subject Re: How do local indexes work?
Date Fri, 30 Jun 2017 05:46:44 GMT
Thanks for the slides, Rajesh Babu.

Does this mean any read path will have to scan all regions of a table? Is
there an optimization available if the primary key and the index share a
common prefix, thus reducing the number of regions to look at?

Thanks again!
