Hi Ian, I am in the process of writing the proposal. So as you mentioned earlier it is better to split this in to 4 sub tasks and 2 before midterm and 2 after mid term.
So in summary I would like to add the subtasks that I feel. Please add anything I am missing or anything required to have. Main tasks overview: 1. Implementing a CassandraResourceProvider to READ from Cassandra. Implementation Details [1] 2. Test with one node Cassandra cluster end to end with the implementation of #1. 3. Enhance CassandraResourceProvider to READ with access control (with latest security related APIs). 4. Enhance CassandraResourceProvider(or may be a new interface for writing i.e CassandraPopulator) to WRITE and WRITE with access control. Here as I feel, #1 and #2 completion will more weight and relatively more time consuming than #3 and #4 (I am not aware of the complexity of incoperating the access control to READ/WRITE). Appreciate your valuable feedback on this, whether this task breakdown is appropriate or not suits to the GSoC time line or anything more to add/remove and etc ?
