Recently get touch with SAP In-Memory Database, play with SQLscripts, R, L and JDBC driver.
Of course, the most exhausted experience is to build up HANA environment.

Though SAP provided with sufficient details in BluePrint, I’m still wondering how to work this out with actual coding. You know, that’s “bad” habits of programmer….

Finally decided to do something, after going through CSDN link – Megastore of Google.

As the most popular distributed no-sql database inherited from Google’s BigTable, open source project Cassandra will be a very good entrance point to learn how-to for Non-sql(Mixed-Mode database). I guess, to some degree, SAP also learnt something from such idea.

In section “distributed database” section of In-Memory database, mentioned a little bit.

Anyway, journey starting…
