# 初始化集群时，集群节点之间同步超时时间：10*2s=20秒
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
# 集群在运行过程中同步数据超时时间：5*2s=10秒

# The number of snapshots to retain in dataDir
# 数据时存在内存里面的，zk会根据事物id机制进行做快照，当快照达到多少个后进行合并
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
# 多久进行一个合并，为0:不进行自动合并  为1:一个小时进行一次判断快照个数是否大于等于3，如果满足则进行合并
#autopurge.purgeInterval=1
