AR Extension, Bulk Upload and Synchronize


I am looking at ActiveRecord Extension

as a way of helping me synchronize data from a csv file. I have the app working using row by row query, but the bulk upload looks like it will help speed things up. There is also mention of a synchronize method. But I have only found limited documentation.

If anyone has any pointers to some docs, or some information on how bulk upload and synchronise work I would be grateful. Will synhronize allow me to send multiple rows in one hit and have the table updated where there are changes, and can I control the direction of changes, ie. csv to db.

thanks Tonypm
