Cassandra uses a filesystem similar to HDFS so, yes, Cassandra, like HBase, can scale. The difference is Cassandra is a solution while Hadoop, HDFS in particular, is a platform. Use Cassandra for specific use cases and access patterns but use HDFS as your data lake. ... View more

@Mehdi TAZI HDFS is not NoSQL. NoSQL solutions place schemas (albeit flexible and loose schemas) on the data and are considered alternatives to traditional relational systems. HDFS is scalable, redundant storage and assumes no structure on the data. Many NoSQL solutions in fact use HDFS for their storage. The point is that when you land your data (pdf, txt, json, xml...) in HDFS you have the flexibility to operate on that data with any tool you choose. In many cases the tools you can use to analyze data structured in a NoSQL solution is limited. If you want to dig further, I suggest reading up on the CAP Theorem. All database systems must adhere to the CAP Theorem. Because HDFS is storage, it doesn't have this limitation. ... View more
