different in full-domain optimization, such as ensuring that algorithms that successfully process a single piece of data can successfully process 10, 100, or even 1 million of data. The event complexity (large o symbol) is the best description, regardless of whether this type of measurement is feasible. Latency is the performance extension killer. You will do all you can to do all the arithmetic processing on the same machine. This is known as vertical scaling (scaling up).If you can drop the p

Http://hi.baidu.com/sunsunsoso/blog/item/b197d6a63193718fd0435814.html Recently, I have been working on the preliminary design of a project. Considering the system expansion and performance problems in the future, I have also found many solutions, one of them is to use the database cache tool memcached (of course, this tool is not limited to the database cache ). Let's briefly introduce what memcached is. Memcached is a high-performance, distributed memory object cache system that reduces databa

1: Please describe the simple principle and application of exception handling mechanism in Java, and explain the difference between error and exception. Every time an exception is generated, if there is no program to handle, then the program will interrupt the phenomenon, then, in fact, once an exception is generated, the JVM will throw an exception class instantiation object, if you use the Try statement t

embodiment of object-oriented thinking. Disadvantages are: Programming is slightly more complex, and you must use the Thread.CurrentThread () method if you want to access the current thread. The advantage of creating multiple threads with the inherited thread class is: Writing is simple and if you need access to the current thread, you do not need to use the Thread.CurrentThread () method to get the current thr

Getconnection () method again. ConnectionPool holds two containers-one queue stores idle connection, and the other vector (taking into account synchronization) stores the connection in use. When the developer uses a database connection, it is fetched from the queue, not returned empty, and the vector is put back when the close connection is completed. ConnectionPool provides a simple dynamic expansion mechanism based on minidle and maxconnection.
