[GitHub] [pulsar] zubchenok opened a new issue, #14721: Broken subsequence of delayed messages
zubchenok opened a new issue, #14721:
URL: https://github.com/apache/pulsar/issues/14721
**Describe the bug**
Delayed messages to shared topic breaks subsequence of messages and delivered earlier than expected.
**To Reproduce**
Steps to reproduce the behavior:
1. Setup local standalone pulsar
2. Send messages every 20ms with the same deliverAt timestamp *10000ms* and with payload of millisecond when sending was started.
3. Log received messages payload.
I start receiving all messages after 9 seconds and it I have in log:
```
9001ms
1ms
21ms
41ms
61ms
81ms
...
8981ms
(here should be 9001ms)
9021ms
9041ms
...
```
**Expected behavior**
Two expectations:
1. Most important I expect first message to be received is message '1ms' and message '9001ms' after '8981ms'.
2. I expect start receiving messages after 10 seconds
Issue is reproduced in 2.8.0 and 2.9.1

Hi, @zubchenok
Sorry for missing this issue.
The second issue:
> I expect start receiving messages after 10 seconds
You can set `isDelayedDeliveryDeliverAtTimeStrict=true` to solve this problem.(broker version greater than or equals to 2.9.3)#16068 or set `delayedDeliveryTickTimeMillis=1`(broker version less than or equals to 2.9.3)

It seems that delay messages should not be strictly guaranteed to be consumed in the order of delayed time. It is only consumed as early as possible.
