Starting today, a daily question continues to be updated: 1. Pointers and reference references always point to an object, there is no null reference, and the pointer can point to an object or point to a null (NULLPTR) pointer can be assignable, and

From a large perspective, Netty performance is mainly reflected in: 1.io threading Model using reactor mode, synchronous non-blocking. This determines that more can be done with the least amount of resources. 2. Memory 0 copies use direct caching 3.

Redis's author, Salvatore Sanfilippo, once compared these two types of memory-based data storage systems: 1.Redis supports server-side data operations: Redis has more data structures and supports richer data operations than memcached, usually in

2011 will be remembered, because this year the SQL will die; this year, the relational database retreated from the first line; this year, developers discovered that they didn't have to convert each object into a table structure to persist data. 2011

We all know that to save some hot data to the cache can greatly improve the speed, then the question is whether to use Redis good or memcached good, the following are some simple differences between them and comparison: 1. Redis not only supports

Before introducing Threadpoolexecutor, you should first understand what executor is. Executor Interface Executor is a task that is used to perform runnable. This interface provides a decoupling about "task submission and task execution", including

In a multi-channel program, you need to read multiple processes to memory from disk at the same time, we need to manage the memory so that the process can be executed in a coherent manner.Usually the instruction is read from memory, decoded, and

There are two basic ways to manage memory in a computer: Segment management and page management. When using a 80x86 microprocessor, the memory address is divided into three different addresses: logical address, linear address, physical address. What

What is the CLR?The code that runs in the. NET framework last time is called managed, and vice versa is called unmanaged code. There are many benefits to unmanaged code,managed code, such as writing in multiple programming languages, improving
