To give some background, Kafka topics are feeds where in messages are produced to and consumed from clients. If the schema disagrees with the data being serialized, it will throw an exception, preventing any malformed data from being written into the Kafka topic. writes the processing results back into Kafka topics.

With event streaming as a managed service, we had no costly new hires to maintain our clusters and no worries about 24x7 reliability., Although we had some experience running open source Kafka ourselves, we recognized that we needed a trusted partner to help us resolve issues that wed encounter with a larger-scale deployment. Event IDs provide a way to uniquely identify each event. To avoid issues it is best to use either, but not both. Note This is a Quick Start for the managed cloud connector. Operational complexity is manageable with open source monitoring tools. For more information about configuring parameters for internal topics, writing, the application users must coordinate topic management. Here are some examples: <project>.<product>.<event-name> <app-name>.<data-type>.<event-name> But events will come from multiple areas of your organization, from different teams and systems, and embedding that contextual data into the name of the event can help with both stream management and discovery. On-Prem. We found that the CNCF landscape is a good advisor when working going into the cloud / microservices space: https://landscape.cncf.io/fullscreen=yes.

Kafka belongs to "Message Queue" category of the tech stack, while Confluent can be primarily classified under "Stream Processing". If you need more capabilities than I'd consider Redis and use it for all sorts of other things such as a cache. Is queuing of messages enough or would you need querying or filtering of messages before consumption? Kafka enforces a set of legal characters that can constitute a topic name. Kafka Topic Naming Conventions: Best Practices - Medium Kafka is a distributed, partitioned, replicated commit log service.
