Issue fixed in 2019.1.19 with open source references where available:

  • Stability: Row cache is incorrectly invalidated in incremental compaction (used in ICS and LCS)  #5956 #6275
  • CQL: (LOCAL_/EACH_)QUORUM consistency calculation is broken when RF=0 #6905
  • Performance:  On Red Hat derivatives, like CentOS used in ScyllaDB Enterprise AMI, tuned service tries to tune the system for maximum throughput, and this conflicts with scylla-kernel-conf’s latency-oriented tuning. #7696
