I believe, additionally, we'll also have to consider how the data access is optimized (availability of streaming, specially since the files can be quite larger), whether the storage option itself is optimized for storing a few GBs of data (if that is part of the requirement), etc as well. So, first, we'd have to check whether Cassandra is capable of handling data contents of few hundreds of MBs (or maybe more than that). I believe, that would/wouldn't make it a valid reason to use HDFS or any other scalable blob store. However, it would be good to check on this a bit more in detail, considering the aspects such as the availability of multitenancy, etc so we can come up with the best suited solution for the problem at hand. Will do a bit of researching and update the thread.
