Hi, When I looking at "countPendingHints" in HintedHandoffManager via jmx, I found that pending hints increases even when my cluster handles only reads with quorum from clients. The count decreases when I see it in long period (e.g., in an hour). But it can increase in several thousands in short period (for instance, in a few seconds. even in minutes some cases). My cluster looks healthy at that time. Is it normal behavior? I thought that hints are created only when data are written and a node is down. Does it increase with read repair? I'm waiting for finishing hinted handoff. But it takes long time. I'm using cassandra 0.7.4.
Best regards, Shtoaro
