Hey Johnny, Sorry for the delay on replying. You might find this talk I did of use https://youtu.be/vE7aKZT9r7k
TL;DR you will need to scale up ZooKeeper (CPU, Memory, Disk) and Brokers (Memory for sure). There's probably more I've forgotten that you'll find in the talk. In the end we would be creating 500k+ topics per day and since tiered storage would still require ZooKeeper to keep track of these topics so we created our own "offloader" to read topics once they are finished and writes the data to S3. -Frank ---- On Thu, 24 Feb 2022 05:08:33 -0500 Johnny Miller <joh...@digitalis.io> wrote ---- Hi - I have a project I am at the design phase in, and it would be interesting to leverage the million topic scale in Pulsar. I have experienced problems in similar tech where these limits are more"hypothetical" rather than real. Is this realistic in prod/operationally? Not necessarily a lot of data, more just lots of topics. Any real stories, experiences or war wounds around this level of scale would be appreciated.
