You can track the number of objects created by a class by using the class's static fields and constructors. Please write a class, and at any time you can query it for "How many objects have you created?"1 Public classDuixiang {2 Public Static voidMain (String args[]) {3Tongji x=NewTongji ();4 X.shuchu ();5Tongji y=NewTongji ();6 Y.shuchu ();7Tongji z=NewTongji ();8 Z.shuchu ();9 }Ten One } A clas

况下进行定期删除： - 每隔一段时间执行一次删除操作，并通过限制删除操作执行的时长和频率，籍此来减少删除操作对 CPU 时间的影响。redis使用的是惰性删除 + 定期删除的策略Case LocatorThrough the above analysis, the problem has been relatively clear, for the following reasons: For some reason, Redis uses more and more memory (possibly due to lazy deletion, resulting in more data expire, or other reasons, depending on the implementation within Redis) Redis does not actually read and write files because it is only a cache, so the operating system does not flush i

the stored procedure have been removed from DMV. It seems that sp_recompile will directly mark the cached execution plan and statements in the cache as unavailable. Therefore, no related records exist in DMV. This means that there is no way to track the re-compilation caused by the re-compilation mode of the stored procedure identity from DMV. So can we track the performance monitor counter "sp recompilati

problem, the more convenient and reasonable way is: Lazy deletion is sometimes not very reliable, especially for some log types of data, after writing to Redis, regardless of, although set the timeout period, but no effect Regular deletion is also not very reliable for expire-keys, there is randomness, it may also expire long data is not deleted Comparatively, a reasonable way is to set the maxmemory size of Redis based on usage to enable Redis to implement its own data cleansi

was quite good. The key point is that you must be able to endure hardships and make the introverted programmer more extroverted, and you will succeed. You are your own salesman. In fact, there are still many ways to do this, but I only want to think about it now. If you are interested, you can contact me again. In addition, if you have not tried it for more than half a year, you should not say that this method is not feasible. This is my practice. The article is written here and may be co
