Re: Fail fast a broker

2018-06-08 Thread Jacob Sheck
What do you mean by "The issue appears when one of the brokers starts being impacted by environmental issues within the server it's running into (for whatever reason)"? You should consider Kafka to be a first tier service, it shouldn't be deployed on shared resources. There are a lot of opinions

Re: what are common ways to convert info on a web site into a log entry?

2018-01-15 Thread Jacob Sheck
You will need to find or create something to accomplish this. Topics in Kafka primarily act as queues. If you search the web for more information about "kafka connector http" you will find a few projects that do this. You could also take a look at the Confluent S3 Connector as an example of how

Re: Is Kafka Streams right for me ?

2018-03-13 Thread Jacob Sheck
Sameer when you say that you need to "consume from and produce to a topic" to me that seems like a good fit for Kafka Streams. Streaming your data out of Kafka for a transform and back in has some fundamental costs and operational challenges involved. Are the events in your stream stateless? If

Re: delivery semantics?

Your question seems to be confusing the producer and consumer responsibilities in message delivery durability. Neha from Confluent wrote a blog post about this which should help your understanding of the how the Kafka clients handle this.

Re: Closing a KafkaConsumer triggers a rebalance in KafkaConsumers subscribed to other topics. Is this the expected behavior?
