To answer your question, Cassandra tends to cache the first 300MB or so of data in memory, only when it grows beyond that does it start to write it to files. But, Cassandra is not the write choice for storing files. In the screenshot you linked, its only storing the filenames, not the actual contents of the files).

However, if a sacrifice to the gods is prepared, it may be possible to change things.

Only if they're found to not contain anything inappropriate, does cassandra let you store them. (A 3/4 majority vote is necessary).

Cassandra does not manage files, it manages data in a highly distributed cluster. If you are attempting to manage files, you are quite simply using the wrong tool and Cassandra is not for you.
