I'm using RF=2 (i know it should be at least 3 but i'm short of resources) and WCl=ONE and RCL=ONE in a cluster of 10 nodes in a insert-only scenario.
The problem: i dont want to use nodetool repair because it would put hige load on my cluster for a long time, but also i need data consistency and fault tolerance in a way that: if one of my nodes fails: 1. there would be no single record data loss 2. write/read of data would be continued with no problem I know that current config won't satisfy No.1, so changed the Write Consistensy Level to ALL and to satisfy No.2, i'm catching exceptions of "1 replicas needed but 2 required", write those records again with WCL = ONE and put them somewhere for rewrite later with WCL=2. Is there anything wrong with this workaround? any better solution (Strong requirements: I can't change the RF, The system should tolerate 1 node failure with no data loss and no read/write failure) ?
