2018-04-03 14:25:23 UTC - Karthik Palanivelu: Thanks @Matteo Merli, my company does not approve a component to launch in prod when in Incubation. April is a good timing as well for me to streamline things at my end. Can you provide me a list or image of list of companies using it in production? ---- 2018-04-03 14:40:12 UTC - Ivan Kelly: @Karthikeyan Palanivelu Yahoo uses it extensively ---- 2018-04-03 14:41:52 UTC - Ivan Kelly: <https://yahooeng.tumblr.com/post/150078336821/open-sourcing-pulsar-pub-sub-messaging-at-scale> <- there's a bit about where they use it here. and that was 2 years ago. ---- 2018-04-03 14:42:21 UTC - Ivan Kelly: I get the impression it's usage has grown a lot there since. but @Matteo Merli can confirm ---- 2018-04-03 19:28:27 UTC - Piotr: It would be very interesting to know who is using it and what they use it for actually :slightly_smiling_face: ---- 2018-04-03 21:14:06 UTC - Karthik Palanivelu: Yes if we get a list who is using it for which use cases will be of great help ---- 2018-04-03 22:14:22 UTC - Igor Zubchenok: Hello guys! A quick question: How to delete a namespace? I send `DELETE <http://vv:8080/admin/namespaces/test-prop/vv/ns>` and I get `Namespace test-prop/vv/ns does not exist.` However I still can get a topic stats with `GET <http://vv:8080/admin/persistent/test-prop/vv/ns/test-topic/stats>` Any thoughts? ---- 2018-04-03 22:21:28 UTC - Igor Zubchenok: I understand that it looks like a probably dumb question, but I quite confused now! ¯\_(ツ)_/¯ ---- 2018-04-03 22:25:56 UTC - Igor Zubchenok: FYI: I didn't created the namespace explicitly. ---- 2018-04-03 22:27:01 UTC - Matteo Merli: @Igor Zubchenok Yes, since there’s no authentication by default, it let’s you create topics even if namespace doesn’t exist.. which can be confusing ---- 2018-04-03 22:27:27 UTC - Matteo Merli: some operations, are checking for the existance of namespace ---- 2018-04-03 22:28:47 UTC - Igor Zubchenok: I see. If I create namespace, it doesn't allow me to delete. I guess namespace should be created automatically in case if I can create topics. What do you think? ---- 2018-04-03 22:30:03 UTC - Matteo Merli: I think the most intuitive way is to have a “default” namespace, that can be useful in a single-tenant deployment ---- 2018-04-03 22:30:23 UTC - Matteo Merli: and then disallow to create topic on a non-existing namespace ---- 2018-04-03 22:33:51 UTC - Igor Zubchenok: This sounds really reasonable for quick-start with Pulsar. ---- 2018-04-03 22:33:58 UTC - Igor Zubchenok: One more question: What's the fastest way to delete all topics in a namespace? ---- 2018-04-03 22:35:39 UTC - Matteo Merli: I though there was a way to do it in one shot… but apparently not. ---- 2018-04-03 22:36:29 UTC - Matteo Merli: there’s an options to drop a subscription from all topics in a namespace:
`bin/pulsar-admin unsubscribe $MY_NAMESPACE -s $MY_SUB` ---- 2018-04-03 22:45:25 UTC - Igor Zubchenok: Is it important to have authentication and explicit namespace creation? I feel I don't need it, cause I have a fully isolated environment. ---- 2018-04-03 23:39:05 UTC - Matteo Merli: authentication is probably not necessary in a single tenant isolated env ---- 2018-04-03 23:39:08 UTC - Matteo Merli: explicit namespace creation (other than a “default” namespace) is useful to avoid confusion on what “exists” and what doesn’t. For the naming, see the proposal at <https://github.com/apache/incubator-pulsar/wiki/PIP-11:-Short-topic-names> which will go into 2.0 release ---- 2018-04-04 01:14:58 UTC - Karthik Palanivelu: @Matteo Merli I have two questions: 1) Can we transmit file as a message say in GB size? 2) Is there any roadmap to create ingestion spec for DB like pipelineDB or Druid? ---- 2018-04-04 01:19:33 UTC - Ali Ahmed: 1) Not really you can configure larger message sizes gigabyte size payloads are not appropriate for messaging systems, for files generally a custom client would split them into smaller chunks for transmission. ---- 2018-04-04 01:21:43 UTC - Ali Ahmed: 2) I am not sure what that has to do with a messaging system, pulsar would be concerned with bytes transferred ---- 2018-04-04 01:23:33 UTC - Matteo Merli: @Karthikeyan Palanivelu actually for large files support we plan to add native support in the near future. ---- 2018-04-04 01:24:24 UTC - Matteo Merli: What do you mean by ingestion spec? Like a connector from Druid into Pulsar? ----
