Issue

  • High write latency outliers as long as a couple of seconds observed
    • It could be as high as the long Consistency Point (CP) duration
    • The average latency might not be significantly higher, but these outliers could lead to client outages if the timeout setting on the clients is low
  • Longer CPs observed along with the high write latency outliers
  • P2_FLUSH phase is elongated leading to the Long CPs
