Solve the problem that the Onlyoffice file version changes and the problem that multiple people cannot edit collaboratively after using dynamic keys
1.Cause analysis Onlyoffice’s file saving mechanism relies on the callback interface to save files. Once the file is saved successfully. When the editor is opened again with the last key and the latest document URL address as parameters, the editor service goes to redis to find the cache based on the key and verifies whether […]

Scheduling yard algorithm (infix expression->prefix/suffix expression)
There are many and detailed reference materials on the dispatch field algorithm on the Internet; and there are other methods to deal with the problem of converting infix expressions into prefix/suffix expressions processed by the dispatch field algorithm. Those who are interested can learn about it on their own. References: Algorithm – Shunting Yard Algorithm […]

Try traffic playback, no need to write annoying automated test cases anymore!
Hello everyone, I am an experienced driver of automated testing. Students who have been exposed to interface automated testing all know that we generally need to write automated cases based on a certain automated testing framework. The basis for writing automated cases comes from the interface document, and the requests in the interface document are […]
13 | With the same essence, why can Spark be more efficient?
In the last issue, we discussed the programming model of Spark. In this issue, we talk about the architectural principles of Spark. Like MapReduce,Spark also follows the basic principle of big data computing that mobile computing is more cost-effective than moving data. However, compared with MapReduce’s rigid Map and Reduce staged calculations, Spark’s computing framework […]
