application interfaces and protocols. It is well known that the lower-level structure provides a broad set of important services: socket and connection management, request and response processing, various security policies, caching and many more enforcement measures. Whenever you initialize an HTTP request or XMLHttpRequest, a persistent service push event or WebSocket session or open a WebRTC connection, we are interacting with some or all of these underlying services.There is no single best p

benefits of HTTP: When considering the compatibility of existing architectures, WebSockets is often a pain point because upgrading HTTP connects to a protocol that is completely unrelated to HTTP. Scalability and Security: network components (firewalls, intrusion detection, load balancers) are built, maintained and configured for HTTP, and large/important programs prefer resilient, secure, and scalable environments. Similarly, you have to consider browser compatibility. View t

at a time (thanks to inline caching). Sequence: Avoid using a sparse sequence of keys that are not incrementing numbers. The number of columns in a sparse sequence that does not contain each element is called a hash table. Accessing the elements in the sequence can be more time-consuming. Similarly, try to avoid allocating large arrays in advance. It's best to increment as you use it. Finally, do not delete the elements in the sequence. This causes the key to be sparse.

The layer-3 switch you know works like this. It works like a layer-3 switch. Why do we say that the L3 forwarding performance of a layer-3 switch is much higher than that of a router? Sometimes it is mentioned in many books that the software of the router is also very powerful and can almost achieve the speed limit forwarding capability. However, it is unlikely that the software can compare with the hardwa

HBase learning Summary (4): How HBase works and how hbase works I. Split and allocate large tables HBase tables are composed of rows and columns. HBase tables may contain billions of rows and millions of columns. The size of each table may reach TB or even PB level. These tables are split into smaller data units and allocated to multiple servers. These smaller data units are called region. The server hosti

Therefore, there should be no loops in your dependency chain. Loops and recursion are not the same,
