- What in-memory databases similar to Redis are available under Windows?
- Which in-memory databases are used under Windows? In-memory databases similar to redis can be divided into relational in-memory databases and key-value in-memory databases. In actual applications, in-memory databases are mainly used with large relational databases such as Oracle or MySQL, focusing on performance. It functions like a cache and does not pay attention to data integrity and data consistency. Key-value-based in-memory databases are easier to use than relational ones, with better performance and scalability, so they are used more in applications than relational in-memory databases. Compare the functional features of mainstream in-memory databases FastDB, Memcached and Redis. The characteristics of FastDB include the following aspects: 1. FastDB does not support client-se

- Comparing server I/O performance of Node, PHP, Java, and Go
- Introduction Understanding an application's input/output (I/O) model means the difference between its planned processing load and brutal real-world usage scenarios. If the application is relatively small and does not serve a high load, it may have little impact. But as the load on your application gradually increases, adopting the wrong I/O model may leave you with many pitfalls and scars. As with most scenarios where there are multiple paths to a solution, the focus is not on which path is better, but on understanding how to make the trade-offs. Let's take a tour of the I/O landscape and see what we can steal from it. In this article, we will compare Node, Java, Go, and PHP respectively with Apache, and discuss how these different languages perform their I/O.
