SmartETL

A light weight ETL engine and smart transformation framework

Build:

From root directory, run: maven install

Run the demo:

  1. Modify distribution/target/SmartETL-0.0.1-incredible/examples/samplejob.xml to have correct path to the sample input files and output location.
  2. Go to distribution/target directory, from command line, run: bin/run.bat

Debug:

  1. Import the projects (libBase, libFormula, smartETL) into Eclipse
  2. Run configuration

Main class: org.f3tools.incredible.smartETL.JobRunner Argument: path to the samplejob.xml, for example: C:\Work\workspace\incredible\examples\samplejob.xml

Nice features:

  1. You can skip predefined amount of top and bottom lines when reading a csv file
  2. You can use lookup as function in formulas
  3. You can setup a filter for input files and smart trans step
  4. Smart trans step allows you define mapping rules using a DSL (domain specific language)
  5. You can filter out a row in formula
  6. All kind of functions such as string manipulation, date time manipulation ... are supported in the DSL
  7. You can define variables in smart trans step. you can use both input data, variables, and output data define output mapping rules
