Yeah, seems to be happening since OP posted. I played the game a few times (3 days in a row). It was fun. But, what I found was strange with the game was the most significant bit was on the right. So, 10000000 was 1 instead of 64; took a while to get used to.

Kafka falls back to an advertised listener, is there a performance penalty?

benjacksondev — Tue, 26 Nov 2024 16:48:36 +0000

In Kafka it will fallback to a different advertised listener if one of them is not available. This is required for us to enable a stretched cluster (brokers on the cluster 1 try to resolve to internal address before trying external address for brokers on cluster 2, vice versa).

Would there be a significant performance penalty when setting up like this, especially if its by design?

I guess it does a nslookup, and if it fails it tries the next advertised listener in the list.

New comment by benjacksondev in "Bash: Creating and Managing Child Processes"

Hey PopGreene, initially, `$child_pid` was set, but I refactored to use `$!` throughout instead. It must have been an oversight when I refactored `$child_pid` out, as the script still passes with the `$child_pid` not set. This is because running `wait` without an argument exits successfully. With `$child_pid` no longer set, it should be replaced with `$!`; otherwise, the script does not wait until the child process is terminated.

To clarify, the `wait` is there to avoid zombie processes, which is the script's intention; it should not be `$child_pid` but instead `$!`.

I've amended the post; thank you.
