Vacuuming out your car? Folding your laundry? We’ve got an audio recommendation for you! This week, listen to (or watch!) Danica Fine’s talk on how client requests work. If you want to get nerdy with us, we’ve also got a blog post on timing wheels and how those support request purgatories. Also, consumer groups are getting a shiny new protocol… learn why!
Today we have a couple of quick usability tips for kcat.
Sometimes, when you're running kcat, you don't want it to be open in the background… you just want to run a command and read the result. In that case, you can add an -e flag to exit, in this case, after printing the last 300 lines from partition 2:
$ kcat -C -b broker_name -t topic_name -p 2 -o -300 -e
You can also view messages in JSON with a -J flag:
$ kcat -b broker_name -t topic_name -J
