Introducing Apache Datafu in two parts, this article describes the part of its pig UDF. The code is open source on GitHub (except for the code.) There are also some slides introduction links).Datafu inside are some of the pig's UDFs. Functions that mainly include these aspects:Bags, Geo, hash, linkanalysis, random, sampling, sessions, sets, stats, URLsA package is appropriate for each aspect.I browsed through all the function source code. In fact, the

When the default UDF export fails, you can try to export the UDF manually by using the manual method, as follows:First upload Udf.dll, connect to MySQL, and then follow the steps below to execute the SQL statement.

Debug|mysql How to debug a MySQL UDF MySQL's UDF is essentially a dynamic connection library that does not need to set an entry point (*nix is called a shared library). Debugging a DLL can be a personal act. Now let me introduce you to a very simple, easy-to-use debugging method. This approach uses the Windows API directly, language-independent, development-tool-independent, project-type independent, and a
