processNodejs encountered I/O event will create a thread to execute, and then the main thread will continue to execute, therefore, take the action of profile to trigger an I/O event, will immediately execute the action of taking timeline, two actions parallel execution, if each need 1S, then the total time is 1S. After their I/O operations are completed, an event, profile, and timeline are emitted, and the event agent receives and continues to perform the subsequent logic, which is the feature

In the design of the database, there are paradigms and anti-paradigm of stress, summarized below. Advantages of the paradigm:1) The normalized database is updated more quickly;2) After normalization, only a small number of duplicate data, only need to modify less data;3) The normalized table is smaller and can be executed in memory;4) Less redundant data, requiring fewer distinct or group by statements when querying.

Disadvantages of non-NMS switches: 1. Non-NMS switches have limited functions and are suitable for household or small-sized networks. 2. ARP protection is not supported. ARP attacks are not a virus, so almost all anti-virus software is helpless. But they are more like viruses-because they can cause slow communication, network paralysis, and information leakage. 3. MAC Address binding is not supported. 4. VLAN division is not supported. When an e

Why create an index? This is because creating an index can greatly improve the system performance. First, you can create a unique index to ensure the uniqueness of each row of data in the database table. Second, it can greatly speed up data retrieval, which is also the main reason for creating an index. Third, it can accelerate the connection between tables, especially in achieving Data Reference integrity. Fourth, when you use grouping and sorting clauses to retrieve data, you can also signific

Index category: Indexes can be divided into clustered indexes, non-clustered indexes, and unique indexes. Advantages: 1. The main advantage is convenient query and improved system performance. 2. By creating a unique index, You can ensure the uniqueness of each row of data in the database table. 3. The data retrieval speed can be greatly accelerated, which is also the main reason for creating an index. 4. It can accelerate the connection between tabl

between the dynamic proxy of JDK and the cglb proxy. In general, JDK proxy is encouraged, because services generally abstract an interface without introducing new things. If it is a legacy system that has not previously implemented interfaces, you can only use cglib. In general, JDK dynamic proxy is preferred. Although its efficiency does not seem to be comparable to that of cglib proxy, its objects can be released normally after they are used up. However, cglib proxy produces a new class for
