You data load is fine. It sounds like you will run into issues with the data model and functionality of cassandra. "Standard Analysis" in the RDBMS sense of throwing any ad-hoc query at the data and letting the query engine work it out is not possible without using HIVE/PIG or some other query language.
You will need to understand what sort of questions you want from the data up from. The best way to learn this lesson is put together and quick prototype and see how the data model works. Hope that helps. ----------------- Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 25/01/2012, at 8:09 PM, francesco.tangari....@gmail.com wrote: > make example of cases please? > > -- > francesco.tangari....@gmail.com > Inviato con Sparrow > > Il giorno mercoledì 25 gennaio 2012, alle ore 05.29, Gustavo Gustavo ha > scritto: > >> That's for sure not much. >> Your rdbms can probably hold the entire dataset in memory, and you can do >> all kinds for queries that you want.
