Slack digest for #general - 2019-11-01
2019-10-31 09:18:08 UTC - Jasper Li: Thanks a lot!!! sorry for asking a stupid question
----
2019-10-31 09:18:43 UTC - xiaolong.ran: Welcome
----
2019-10-31 10:17:40 UTC - Jasper Li: Hello,
I would like to ask that what does it means "Offload has not been run for persistent:// since broker startup" after I set the configuration.
----
2019-10-31 10:53:43 UTC - xiaolong.ran: ```
Offload has not been run for
```
means the offload `NOT_RUN`
----
2019-10-31 10:57:42 UTC - xiaolong.ran: you can use `<https://pulsar.apache.org/docs/en/pulsar-admin/#offload>` or you can config offload to run automatically <https://pulsar.apache.org/docs/en/cookbooks-tiered-storage/#configuring-offload-to-run-automatically>
----
2019-10-31 11:02:08 UTC - Mark Marijnissen: What parameter does `/admin/v2/persistent/{tenant}/{namespace}/{topic}/subscription/{subName}/resetcursor/{timestamp}` accept as timestamp?
I tried using `24h` but that does not seem to work. An integer works, but I am unsure what I am doing.
See <https://pulsar.apache.org/admin-rest-api/?version=2.4.1#operation/resetCursorOnPosition>
Documentation is confusing:
integer <int64> Required
time in minutes to reset back to (or minutes, hours,days,weeks eg:100m, 3h, 2d, 5w)
----
2019-10-31 11:04:51 UTC - tuteng: timestamp is a unix timestamp var timestamp = Math.floor(dateTime) - parseInt(this.form.minutes) * 60 * 1000
----
2019-10-31 11:07:08 UTC - Mark Marijnissen: thanks!
seems the CLI does a conversion from relative time to unix timestamp in millis:
<https://github.com/apache/pulsar/blob/b2aae9c3571f3bc9516a42a794c75d44e6d16e9f/pulsar-client-tools/src/main/java/org/apache/pulsar/admin/cli/CmdTopics.java#L527-L530>
So the REST API docs only work for the CLI, not for the pure REST API
----
2019-10-31 11:14:11 UTC - tuteng: I think if you use java for development, you can try to apply pulsar-admin <https://mvnrepository.com/artifact/org.apache.pulsar/pulsar-client-admin>. If you use go for development, you can try to apply pulsarctl <https://github.com/streamnative/pulsarctl>. Other languages need to call rest api to implement it.
----
2019-10-31 12:21:49 UTC - Mark Marijnissen: I have a little nodejs commandline utility for pulsar developers to check stats, peek a message, etc.
+1 : tuteng, Jasper Li

2019-11-01 07:11:37 UTC - Gopi Krishna L: Hello Everyone!
Is there any specific project structure for writing pulsar-functions in java. And where can I find a tutorial for the same. I am trying to do a POC on pulsar compared to spark, anyone who can guide me through the streaming data from mongoDB ?
