TIDB The Large Scale Relational Database Solutionand/or databases that require processing securely at very high speeds queries. TiDB focuses on scalability, database clustering, and its ability to automatically scale horizontally (across nodes/instances/machines) product, but is meant to serve a specific market. It is important to note that merely based on its scalability and its ability to process at speed TiDB is not particularly novel, other options in the market defining TiDB features full scalability in that its mark-out feature is horizontal scalability (across nodes) but it also features the much more common vertical scalability. This is present in many database0 码力 | 12 页 | 5.61 MB | 1 年前3

面向亿行 C/C++ 代码的静态分析系统设计及实践-肖枭existing work cannot escape from the "pointer trap" – a precise points-to analysis limits its scalability and an imprecise one seriously undermines its precision. We present PINPOINT, a holistic approach decades. Existing work suffers from an unresolved paradox – a highly precise analysis limits its scalability and an imprecise one seriously hurts its precision or recall. In this work, we present SMOKE, a sensitive analysis to achieve high precision. However, they are known to easily suffer from scalability issues, especially for whole-program analysis. For example, SATURN [3] is reported to spend more0 码力 | 39 页 | 6.88 MB | 2 年前3
