An alternative paradigm was ultimately offered by Albert Einstein, then a 26-year-old patent clerk in Bern, Switzerland. His theory of special relativity posited two principles: that the laws of physics are the same in every uniformly moving frame, and the speed of light in a vacuum is the same for all such observers. Through these principles, Einstein was attempting to introduce “a simple and consistent theory,” by which “the introduction of a ‘luminiferous ether’ will prove to be superfluous.”。关于这个话题，viber提供了深入分析
turbolite has an experimental semantic predictive prefetching feature that tracks cross-table access patterns using a lightweight prediction engine held as a trie in the manifest. When queries consistently touch the same set of tables together (e.g. users then posts then likes), future queries that touch any subset trigger background prefetch of the rest. See Predictive Prefetching for details.，推荐阅读Line下载获取更多信息
