Dynamic | The main idea of the data has been solved, the following start to write detailed design (in the Sybase ASE database for example, others to expand): 1. Establish the middle-tier table vdt_columns, which is used to build the column data in the pipeline. To perform similar code generation: Ls_sql = "CREATE Table Vdt_columns" (" Ls_sql + = "UID int nul

, Memoryrecoverchannel, FileChannel. Memorychannel can achieve high-speed throughput, but cannot guarantee the integrity of the data. Memoryrecoverchannel has been built to replace the official documentation with FileChannel. FileChannel guarantees the integrity and consistency of the data. When configuring FileChannel specifically, it is recommended that the directory and program log files that you set up

A recent project uses the Kafka client to receive messages, requiring that they be written to the file (in order). There are 2 ideas: 1. Use log4j to write the file, the advantage is stable and reliable, the file according to the setting, automatically separates the size. The disadvantage is that there is no way to do when writing files to a certain number or a certain amount of time, automatically switch the function of the directory. If you are loop
