Hi – If I configure a RF across 2 Data centres as below and assuming 3 nodes per Data centre.
DC1: 2, DC2:2
I do a write with consistency level – local_quorum which ensures that there is no inter DC latency. Now say 2 nodes in DC1 crash and I am doing a read with CL = One. Will it return failure to client since the data is now only present in DC2 ? So I would need to do a read with CL = ALL/EACH_QUORUM to ensure that I always get the data even in case of crashes in the local DC ?
