Hi,
Have you explored the below properties of data flow task? This helps to manage the memory while dealing with a huge data load.
BLOBTempStoragePath and BufferTempStoragePath
They define where on the hard disk(s) to page buffer data to. BLOBs (text, next, image) are written to BLOBTempStoragePath l, All other buffer data will be swapped to BufferTempStoragePath
If you have already tried that, then it's better to load data in chunks.
