Siying Dong 8425c8bd4d BlockBasedTableReader: automatically adjust tail prefetch size (#4156) ... Summary: Right now we use one hard-coded prefetch size to prefetch data from the tail of the SST files. However, this may introduce a waste for some use cases, while not efficient for others. Introduce a way to adjust this prefetch size by tracking 32 recent times, and pick a value with which the wasted read is less than 10% Pull Request resolved: https://github.com/facebook/rocksdb/pull/4156 Differential Revision: D8916847 Pulled By: siying fbshipit-source-id: 8413f9eb3987e0033ed0bd910f83fc2eeaaf5758		2018-07-20 14:43:37 -07:00
