Hopefully, it will be an awesome Framework to do ETL with Ruby. It should only work with Ruby 1.9.
You should not trust it, until I clean it up.
For better examples and documentation, refer to the features folder.
I have in mind something like this:
/itiel_example/
|~config/
| `-sources.yml
|~lib/
| `-transformation_class1.rb
|~jobs/
| `-main_job.rb
|~tasks/
| `-itiel.rake
|-Gemfile
|-Gemfile.lock
Take care of defining and running the jobs. It's where you put all the code like the example above.
itiel new project_name.
Use thor?
rake itiel:run
Picture yourself migrating form SQL to Mongo
Some on my mind:
Itiel::Joins::DatabaseTable
Itiel::Lookups::DatabaseTable
Itiel::Loads::FTP
Itiel::Loads::HTTPRequest
Itiel::Loads::MongoDBDocument
Itiel::Script::ExecuteInSystem
Itiel::Extracts::HTTP
Itiel::Extracts::MongoDBDocument
Itiel::Transforms::CustomSort
Itiel::Transforms::MapValues
Itiel::Transforms::IfNil
Just ideas, I have nothing on how to implement most of them
If the column X has a value of Y, send true output to this step, send false output to this other steps
Can't have ETL without these
So you can TDD your ETL
It would be extra nice if all the steps logged statistics
- Processing X rows of Y
- Time spent
- Transformation Name
- Configurable log level
rake itiel::graph
Creates a graphical representation of your ETL flow
Not really, Ruby 1.9 is enough. I don't have plans to make it work on 1.8
