Nginx is a short, very powerful Web server that can also be used as a reverse proxy server and a mail server. In addition Nginx can also be used to build a simple streaming media server. Based on this, this article describes the construction of a simple streaming media server on top of Nginx 1.8, and proxies it to a streaming media server by means of a reverse pr

Label:What is the latency between the PostgreSQL database stream replication master and standby and should be evaluated for both HA and load balancing. A simple HA architecture, for example, is how much time we allow for data loss in the event of a failure of the main library. No nonsense, go directly into this experiment test. Test environment:Main Library: Memory: 32g,cpu:8 Core, ip:192.168.122.101 Standby: Memory: 32g,cpu:8 Core, ip:192.168.122.102 Database configuration: Default Test Prepara

Because of the differences between relational database manipulation languages and object-oriented languages, we still need to spend a lot of time building a bridge between database and Java applications. In general, we can write our own mapping layer (mapping layer) or use a third party ORM (Object Relational Mapper) Object Relational mapping framework, such as Hibernate. ORM frameworks are easy to use, but how to

1. Join for different time slice data streams
After the first experience, I looked at Spark WebUi's log and found that because spark streaming needed to run every second to calculate the data in real time, the program had to read HDFs every second to get the data for the inner join.
Sparkstreaming would have cached the data it was processing to reduce IO and increase the speed of computation, but since our scenario now is to inner join with data strea
As a basic functional unit to serve the users, the performance of the streaming media server directly affects the service capability of the streaming media system. In the measurement of streaming media server, the most important indicator is the flow of output capacity and the number of concurrent requests can be supported, the following we take the local hard di

of queries per second, and each page may contain multiple ads. To handle user feedback in a timely manner, a low latency, scalable, and highly reliable processing engine is required. However, for these applications with high real-time requirements, although MapReduce has made real-time improvements, it is still difficult to meet the application requirements stably. Because Hadoop is highly optimized for batch processing, MapReduce systems typically operate static data by dispatching bulk tasks,
