We can use cassandra in our project to store huge data like user information, product catalog etc., which is very easy for us because of its scalability feature as well with out other dependencies we don't need any additional software or framework while using it so this makes things easier by doing that alone without depending upon some frameworks/libraries.
I have not found anything negative about cassanda container solution yet but i think if you are looking into solving your storage needs then go ahead otherwise there will be no point at all thinking twice before selecting CASSANDRA AS A STORAGE SOLUTION! It's great database engine where one could easily perform CRUD operations within seconds instead waiting hours (or days) when performing same operation manually via JDBC driver connection.
