ETL ConsiderationsAs a data warehouse system, ETL is the key link. Said Big, ETL is a data integration solution, said small, is to pour data tools. Recall the work over the years, the processing of data migration, conversion is really a lot of work. But those jobs are basically a one-time job or a small amount of data, using Access, DTS, or making a small program

Check whether the empty line ETL processing in kettle data streams sometimes requires data generation but no data input. This may cause some problems. Therefore, the ETL data stream is usually required to generate a blank line of data; sometimes some clustering functions are required for processing, which means that when no data is input, the generated value is 0
