Vlad Zolotarov	d56684b1a5	sstables::shared_index_list: use utils::loading_shared_values ... Since utils::loading_shared_values API is based on the original shared_index_list this change is mostly a drop-in replacement of the corresponding parts.

Tomasz Grabiec	1dbd2e239e	sstables: index_reader: Share index lists among other index readers ... Direct motivation for this is to be able to use two index readers from a single mutation reader, one for lower bound of the range and one for the upper bound of the range, without sacrificing optimization of avoiding index reads when forwarding to partition ranges which are close by. After the change, all index readers of given sstable will share index buffers, so lower bound reader can reuse the page read by the upper bound reader. The reason for using two readers will be so that we are able to skip inside the partition range, not only outside of it. This is not possible if we use the same index reader to locate the upper bound of the range, because we may only advance the cursor.	2017-03-28 18:10:39 +02:00
