kafka brokers bind to many networks, does it work?


kafka brokers bind to many networks, does it work?



what if a cluster is bind to more than one subnet with different ip addresses for every broker, a dns name for every ip addr. ? This is inside the overall company network (dns included), no exposure to public network. No routing among subnets.
Is it possible to configure the cluster in order to not make a mess and respect configured networking?
I mean, I configure listeners with the names of the internal subnet (the one with kafka brokers and zookeeper servers) and external listeners with the names of every subnet the broker is bind to.
Supposed configuration (part of):


advertised.listeners=EXTERNAL://broker1.subnet1.localdomain:9993,EXTERNAL://broker2.subnet1.localdomain:9993,EXTERNAL://broker1.subnet2.localdomain:9993,EXTERNAL://broker2.subnet2.localdomain:9993,EXTERNAL://broker1.subnet3.localdomain:9993,EXTERNAL://broker2.subnet3.localdomain:9993,INTERNAL://broker1.internalsubnet.localdomain:9990
inter.broker.listener.name=INTERNAL
listener.security.protocol.map=EXTERNAL:SSL,INTERNAL:PLAINTEXT



Make sense?

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false.

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
