Hello everybody ?!|
I've just realize a SpreadSheet metamodel which defines concepts that we found in an Excel File for example.
Il I want to import an Excel file in my model, I import it using the 'Apache POI' API, I read my file, I fill my model and I save it in a ressource (XMI). The model creation is quick enough but the save step is very very slow... I need about one minute to save "only" 1000 rows of my file (30cells by row). Each cell have a reference on a line and on a row, but I think that's too much... With this rythm, I need 16 hours to read one milion of rows...
Do you think that's normal or are there some optimization to this save step?!
Thank you for your answers!
