(which avoids lambda allocations for methods likeOption.exists).inline-scalais only safe if the Scala library version is the same at compile time and runtime. Since we cannot guarantee this for all cases (for example, users may depend on the kafka jar for integration tests where they may ...
Flux also supports variable substitution at run-time, which is used in this example.Both topologies use the dev.properties file at run time to provide the values for the following entries in the topologies:${kafka.topic}: The name of the Kafka topic that the topologies read/write to. ${...

As we’ve seen from the previous example, the data received by the consumer isn’t exactly “real time”. The consumer polls the Kafka brokers to check if there is enough data to receive.The minimum buffered bytes defines what “enough” is. For example, if we have a configuration like ...
Let’s take a look at the scenario of wallet transaction processing – The goal of this use-case is to process the wallet transaction and notify users via email /sms/in-app. This is a fictitious example to showcase the Kafka trigger and output binding usage with Avro and...
In this tutorial,we saw how we use Kafka to do exactly this, using transactions, and we implemented a transaction-based word counting example to illustrate the principle. Feel free to check out all thecode samples on GitHub.

This is a fictitious example to showcase the Kafka trigger and output binding usage with Avro and header data. The code can be further customized and extended as per your requirements. The wallet producer helps generate wallet transactions in the Avro serialized format to kafka to...
