  • MB-11661:  mem_used in increasing and dropping in basic setup with 5 buckets
  • MB-11621: Rebalance fails when adding node back after failover (delta recovery) due to "{badmatch, {error,{failed_nodes,['ns_1@172.23.96.14']}}}"
  • MB-11582: tmp_oom errors due to spike in memory usage during delta recovery
  • MB-11405:  ~2400% CPU consumption by memcached during ongoing workload with 5 buckets

    • Views


    • MB-10273:   View compaction should be triggered predictably, especially with parallel compaction enabled

    • MB-11643: Incoming workload suffers when XDCR enabled
    • MB-11435: 1500-2000% CPU utilization by beam.smp on source nodes in XDCR scenarios (was ~500% in 2.5.x)
    • MB-11434:  600-800% CPU utilization by memcached on source nodes in XDCR scenarios (was <100% in 2.5.x)
    • MB-11382:  XDCR: default replicators per bucket is now 16 (earlier: 32)
