we have use cassandra as object store for some years, you can just split the object into some small pieces. object got a pk, then the some small pieces got some pks ,object's pk and pieces's pk can be store in meta table in cassandra, and small pieces's pk and some pieces store in data table. we store videos ,picture and other no structure data.
