Cassandra - save file
You (and other future readers) might also try using the COPY command of cqlsh.

For example, if you have a local file named "filedata.csv", containing e.g.:

123-45-678-9,some file data here
abc-de-fgh-1,some other file data here


where the CSV fields corresponding to the columns in your file_uuids table, then you should be able to use:

cqlsh&gt; COPY file_uuids FROM 'filedata.csv';


Hope this helps!
