I had been exploring best possible ETL tools for extracting data from Oracle and loading it to SQL Server.(initial load approximate 200GB data/20-25 oracle tables) We already have SSIS licence but we had been exploring better options. We have to create a near real time data warehouse(loading every 5 minutes or less). Can we achieve it using Pentaho Community Edition or we need to buy the enterprise edition?
We can also explore other better options apart from Pentaho and SSIS.
