CentOS7、Standalone OpenWhisk

I plan to send a message to Kafka in openwhisk, the data flow process is: WSK CLI -> OpenWhisk action -> kafka-console-consume.

But there will be intermittent failures in the process，such as: I send "test01"~"test06", only get "test02"、"test04"、"test06".

According to the log , The cause of the failures is a timeout.

This is my action script:

Hello my fellow developers!

So I've been working on this app for a while now. I like to be up to date with the frameworks I use, so I regularly update when the frameworks release a new version. i.e. Angular 9 > 10. Angular 10 > 11.

So I just recently updated to Angular 11 and updated my nestjs and nx. And now when I try to serve my frontend app, Ivy seems to complain a lot.. but a.. lot... about modules that are not used in the frontend app.

I get this error when I try git pull origin main. It does not even says why it's aborting. I even tried git reset but giving same error. What should I do? Please help.

I've not been able to find an answer to this in the kafkajs docs or from skimming through the official Apache Kafka design docs, but in their producer examples, the producer disconnects after sending the messages. However, that could be because it's a trivial example, and not a long running process.

For long running applications, like web apps, I'm wondering if it is better to disconnect from the producer after sending messages, or if it is better to (presumably) keep the connection open throughout the life of the running application.

An obvious advantage to keeping the connection open is that it wouldn't to reconnect when sending messages, and an obvious disadvantage would be that it holds a TCP connection open. I don't know how big of an advantage or disadvantage either are.

My guess would be that it depends on the expected volume; if the application is going to be constantly sending messages, it'd be best to keep the connection open, while if it is not going to be sending messages frequently, it would be appropriate to disconnect after sending messages.

Is this an accurate assessment? I'm more wondering if there are nuances that I've missed or made incorrect assumptions.

I am dynamically creating a series of topics using KafkaJS, and found that in order to do so without creating election problems I should use the createTopics admin feature.

The issue is that if createTopics is called on a topic that already exist, it does not just return false (as is documented), but it also emits an error stating "Topic with this name already exists".

I am using kafkajs to write to some dynamically generated kafka topics.

I am finding writing to those topics immediately after registering my producer will regularly cause an error: There is no leader for this topic-partition as we are in the middle of a leadership election.

The full error is:
