What are the characteristics of a distributed database system?

The characteristics of the distributed database system are: 1. High reliability, even if a certain node fails, it will not affect the normal operation of the entire system; 2. High performance, multiple nodes work at the same time; 3. Strong scalability, Increase or decrease the number of nodes at any time to meet changing needs; 4. Balanced data distribution, data is distributed on each node to ensure that the amount of data in each node is relatively balanced; 5. Allow distributed transactions; 6. Support remote access, Achieve multi-machine collaborative work.

What are the advantages and disadvantages of PostgreSQL and MySQL?

1 Introduction: Because the company has been using PostgreSQL for a long time, it is busy with function development and has no understanding of some of the advantages and disadvantages of PostgreSQL. Because when developing code, mybatis cannot sense the underlying database used, and the developed code has not changed at all, so there is no Have an in-depth understanding of its underlying PostgreSQL. If you have been using mysql in the past, the basic values of the underlying principles include a series of algorithms. So both postgresql and mysql are free and powerful open source databases.

How to apply the 5 data types in Redis

Problems with the MySql+Memcached architecture. In fact, MySQL is suitable for massive data storage. Hotspot data is loaded into the cache through Memcached to speed up access. Many companies have used such an architecture, but as the amount of business data continues to increase, and access As the volume continues to grow, we have encountered many problems: 1. MySQL needs to continuously remove databases and tables, and Memcached also needs to continue to expand. The expansion and maintenance work takes up a lot of development time. 2. Data consistency issues between Memcached and MySQL database. 3. Memcached data hit rate is low or the machine is down. A large number of accesses directly penetrate to the DB, and MySQL has no
