It’s ComicShannsMono. In theory, Comic Sans is recommended for accessibility by the British Dyslexia Association. I started using it as a childish joke, but it ended up becoming my preferred font because I find it easier to read and less tiring than more traditional fonts.
In any case, your feedback is good. I’ll change it to use whatever font the user has defined. That’s the right approach.
This library lets you process messages in parallel via a single Kafka Consumer meaning you can increase consumer parallelism without increasing the number of partitions in the topic you intend to process. For many use cases this improves both throughput and latency by reducing load on your brokers. It also opens up new use cases like extreme parallelism, external data enrichment, and queuing.
I'm afraid the article is also wrong, this is a typical misconception when working with Kafka. Offsets are committed in the next poll() invocation. If the previous messages weren't processed, a rebalance occurs and messages are processed by other instance. This is an implementation detail of the Java client library but it allows the at-least-once semantic with auto-commit. The book Effective Kafka has a better explanation.
librdkafka isn't part of official Kafka so it may have problems with this as it has other limitations.
In any case, the report isn't right about this and it doesn't use the safest options. Commit offsets manually is the most flexible way but it isn't easy, being the error more usual to commit offsets individually
This report seems to have some wrong insights. Auto-commit offsets doesn't imply dataloss if records are processed synchronously. This is the safest way to test Kafka instead of commit offsets manually
In any case, your feedback is good. I’ll change it to use whatever font the user has defined. That’s the right approach.
