生产者使用异步发送的消息如果因为超时造成发送失败那么

生产者发送海量异步的消息,但是出现如下提示:
2022-10-21 15:22:14.652 INFO 29596 — [ulsar-timer-6-1] o.a.p.c.impl.ProducerStatsRecorderImpl : [myTopic1] [standalone-1-5] Pending messages: 2839252 — Publish throughput: 95439.60 msg/s — 17.07 Mbit/s — Latency: med: 0.000 ms - 95pct: 0.000 ms - 99pct: 0.000 ms - 99.9pct: 0.000 ms - max: -∞ ms — BatchSize: med: 638.000 - 95pct: 1000.000 - 99pct: 1000.000 - 99.9pct: 1000.000 - max: 1000.000 — MsgSize: med: 15057.000 bytes - 95pct: 24000.000 bytes - 99pct: 24000.000 bytes - 99.9pct: 24000.000 bytes - max: 24000.000 bytes — Ack received rate: 0.00 ack/s — Failed messages: 8320115 — Pending messages: 2839252

提示send time out,failing失败了,那么:
(1)发送失败的消息还是保存在持久化类型的主题中吗
(2)如果保存,那么曾经发送失败的消息是否能自动重新发送呢?

感谢。
