memory is private, and different application instances (processes) retain their own private caches, which can easily result in inconsistent data, so it is necessary to set the data to a shorter expiration time, thus increasing the frequency of synchronizing data from the storage space. For this scenario, you can refer to the implementation principle of distributed cache.PS: recently, and colleagues have discussed related topics, caching this thing with Storm, spark the rise of the role not only

, cardinality estimation is a hot research area. We have used this study to provide an open source implementation of cardinality estimates, set element detection and TOP-K algorithms. The cardinality estimation algorithm is the use of accuracy in exchange for space. To illustrate this point, we use three different computational methods to count the number of different words in all Shakespeare's works. Please note that our input dataset adds additional data to the problem with a higher reference

Generally if we write a counter method ourselves, we need to consider thread safety issues, especially when high concurrent access.Atomiclong has handled concurrency problems and is used directly.

In the late half of the last century, a very hot "intelligence show", called "jeopardy!", appeared on NBC television (Gane). In short, in the TV show, the game of two people, a contest is the "answer" question, in the limited time, the first to give the answer score. In an "intelligence show" scored the most wins, and the bonus is not cheap. Whether the Watson intelligent system created by IBM can win this TV show. In other words, any question of natural language expression can be quickly an

ASP is a dynamic site design technology based on Windows NT 4.0, Windows 9X, which enables us to create dynamic, interactive, high-performance Web applications. Compared with traditional dynamic technologies, ASP has the features of direct and HTML integration, easy to create, no need for manual compilation, object-oriented and easy to function extension through active Server component, so it is internet/in enterprise class There is a bright future in intranet applications. However, for differe
