Hi,
I have a query regarding the published message for UI channels
In a use case , if notification is published but there is no user logged in or subscribed to that channel.
will this message be lost after certain time or it will sit in the server until some one subscribe and consume it?
is there any timespan defined to published notifications?
Thanks.
@Prudhvi.Athapu if browser client couldn’t establish a connection(using websocket which is usual connection establishment immediately after the requestor login), then long polling connection is used. Here message will be sent to the client browser without needing of any request from the client, once the published message in the node finds appropriate subscriptions to this published messages. So messages won’t be staying in the server. It will be somehow sent to the client. If we have
Please refer connection topic in the below URL.
Above explanation is for, we have configured subscription, but user has not logged in or request doesn’t reach server.
If suppose, those messages are not consumed itself, for the performance of disk storage pega keeps messages in kafka cluster for 2.5 days to be available for consuming. This retention period can be changed in prconfig.xml.
Please refer below URL for retention period of kafka Topic messages in cluster.
