From test results, it turns out that\nincreasing 1) the persistence queue size threshold on the master and\n2) backoff sleep time on the slave show the better behavior especially\nduring and right after rebalance. However, for the take-over vbucket,\nif the take-over operation is about to being completed, we set the\nbackoff sleep time to 0.5, so that we can reduce the time in the\nstate of dead vbucket on the source and pending vbucket on the\ndestination.\n\nChange-Id: I0f0682a3294f430ccbe36988d47895a437b670ca\nReviewed-on: http://review.membase.org/6155\nReviewed-by: Bin Cui <bin.cui@gmail.com>\nTested-by: Chiyoung Seo <chiyoung.seo@gmail.com>","Chiyoung Seo"]],"repo":"membase/ep-engine","actor":"ns-codereview","ref":"refs/heads/master","size":1,"head":"52d6bd82e402deeea82fb3189be4dcab01da03e8","actor_gravatar":"b3e76bae137f93839c7d251015b22e4f","push_id":31336162}
