Hi, The question I am asking is a bit about the design of a data access objects layer on top of a cassandra datastore.
I had a look at project Kundera which basically implies JPA approach by creating POJOs and mapping them through annotations. Looks promising but what if I would like to have new columns inside the data store(i.e. an attribute of a pojo class) without changing the codebase? How could I achieve such an extensiblity on the DAO layer? What would be the most relevant design pattern? Please do not take the question regarding Kundera, it was just an example. The eventual design should let me CRUD POJOs while gaining an ability to be extended. Regards, Selcuk
