# 这个参数定义了poll方法最多可以拉取多少条消息默认值为500。如果在拉取消息的时候新消息不足500条那有多少返回多少如果超过500条每次只返回500。
# 这个默认值在有些场景下太大有些场景很难保证能够在5min内处理完500条消息
# 如果消费者无法在5分钟内处理完500条消息的话就会触发reBalance,
# 然后这批消息会被分配到另一个消费者中,还是会处理不完,这样这批消息就永远也处理不完。
# 要避免出现上述问题提前评估好处理一条消息最长需要多少时间然后覆盖默认的max.poll.records参数
# 注需要开启BatchListener批量监听才会生效如果不开启BatchListener则不会出现reBalance情况
max-poll-records: 3
properties:
# 两次poll之间的最大间隔默认值为5分钟。如果超过这个间隔会触发reBalance
max:
poll:
interval:
ms: 600000
# 当broker多久没有收到consumer的心跳请求后就触发reBalance默认值是10s
session:

ms: 10000
listener:
# 在侦听器容器中运行的线程数,一般设置为 机器数*分区数
concurrency: 4
# 自动提交关闭,需要设置手动消息确认
