Hello guys, we create flows to deal with big time series of GeoTIFF rasters (treated as xarrays). What do you suggest about passing massive data between tasks? Is better to store those files on S3, EFS temporarily or treat them as a regular file and return them from functions?

Hi @Giovanni Giacco — you’ll almost certainly run into memory issues if passing large data objects between tasks because they’ll be persisted as flow results. I’d recommend passing a file reference.

Thank you Michael for the suggestion. We (me and @Marco Petrazzoli) will proceed with a file reference.
