  • How to update data in maxcompute non transaction table

    Time:2022-7-23

    Introduction: This article mainly explains how to update data through insert overwrite background For most storage formats in big data, supporting random updates is very complex. It needs to scan large files. Maxcompute has introduced the latest function. Transactional tables can support update and delete statements, but the update and delete functions are not suitable […]

  • Eight software development process models

    Time:2022-7-5

    preface The so-called software process model is a development strategy, which provides a set of models for each stage of software engineering to make the progress of the project achieve the desired purpose. For the development of a software, no matter its size, we need to choose an appropriate software process model, which is based […]

  • Transform+asm a small trial

    Time:2022-6-25

    problem I’ve been listening to them talk about function instrumentation, bytecode instrumentation, and ASM. I always feel very powerful and tall. I know the general meaning, that is, java files are compiled into bytecode, and bytecode is modified to achieve the purpose of modifying functions. Today, I’ll try a demo level project to package apps, […]

Give you an n x n integer matrix grid with subscript starting from 0, where grid[r][c] represents the height of the building located in row R and column C.The skyline of a city is the […]

  • 5. C language Hill sorting algorithm

    Time:2022-6-11

    The hill sorting method is used to sort a group of data from small to large. The data are 69, 56, 12, 136, 3, 55, 46, 99, 88 and 25 respectively. Implementation process: (1) The custom function shsort() implements Hill sorting. (2) The main () function is used as the entry function of the program. […]

    This paper introduces the continuous optimization and evolution of Flink Hudi’s original incremental computing model based on mini batch through flow computing. Users can write CDC data into Hudi storage in real time through Flink SQL, and Hudi native supports CDC format in the upcoming version 0.9. The main contents are as follows: background Incremental […]

  • [PHP data structure] insert sort: simple insert and sort

    Time:2022-4-11

    Finally, we have entered the learning of our sorting related algorithms. I believe that friends who have learned the algorithm systematically or have not learned the algorithm systematically will have heard of many famous sorting algorithms. Of course, our introduction today is not to start with the most common algorithm, but to introduce it one […]
