I opend the debug log, and found the message will be ignored, so the
consumer won't receive the message.
[pulsar-client-io-36-5:ConsumerImpl] - [my-sub] [d0201] Ignoring message
from before the startMessageId: 3:999:-1:-1
ConsumerImpl#messageReceived
``` java // If the topic is non-persistent, we should not ignore any
messages.
if (this.topicName.isPersistent() && isSameEntry(msgId) &&
isPriorEntryIndex(messageId.getEntryId())) {
// We need to discard entries that were prior to
startMessageId
if (log.isDebugEnabled()) {
log.debug("[{}] [{}] Ignoring message from before the
startMessageId: {}", subscription,
consumerName, startMessageId);
}
uncompressedPayload.release();
return;
}
```
But the MsgBacklog is always not correct. For NonDurable subscription, we
don't save the cursor info, and I still don't know how to solve this problem.
