2018-04-09 17:10:50 UTC - Karthik Palanivelu: Hi All, I tested the above scenario. Only global cluster gets replicated. How could I achieve the same in topics created local to cluster in different datacenter's? Because, when us-east-1 of aws is unavailable, I should be having my application running from us-west with the same set of data with no data loss. Please advice ---- 2018-04-09 17:13:13 UTC - Karthik Palanivelu: Hello all, Can you please let me know how I can consume all the messages that are not consumed yet? For example, I produced x set of messages with no consumers. After producing messages, when client comes online as Shared/Exclusive not consuming the messages. It consumes messages that were produced after consumer is live. Please let me know if I am missing any. ---- 2018-04-09 17:27:30 UTC - Karthik Palanivelu: @Karthik Palanivelu uploaded a file: <https://apache-pulsar.slack.com/files/U7VRE0Q1G/FA3DN78KE/-.txt|Untitled> ---- 2018-04-09 17:28:10 UTC - Karthik Palanivelu: This seems like I need to have all my topics in global namespace. ---- 2018-04-10 00:48:13 UTC - Sijie Guo: @Karthikeyan Palanivelu
yeah only global namespaces are able to configure cross-datacenter replications. if you want to have a namespace replicated to multiple datacenters, you need to create the namespace under global. “global” cluster just means the replication configuration is stored globally, so every data center is in-sync with replication settings. but you can still configure namespaces to only replicated between specific clusters. “global” vs “local” are kind of legacy concept when pulsar was intiailly developed at yahoo. at the coming pulsar 2.0 release, we are removing “cluster” concept. but for now, using 1.2x version, you need to make the namespace under “global” scope in order to replication. ---- 2018-04-10 00:49:06 UTC - Sijie Guo: > Hello all, Can you please let me know how I can consume all the messages that are not consumed yet?

Please let me know if I am missing any. if a subscription is first time, the consumer starts from the latest message (by default) at the point that subscription was created. You can configure to start from earliest message. Or you can rewind the subscription back at time using bin/pulsar-admin. ---- 2018-04-10 06:55:54 UTC - Mate Varga: @Mate Varga has joined the channel ----
