Apache Kafka, on the other hand, takes additional effort to set up, administer, and support. Right? For Kinesis, scaling is enabled by an abstraction of the Kinesis framework known as a, Unfortunately, selecting an instance type and the number of brokers isnt entirely straightforward. Managing and debugging becomes increasingly difficult for companies while scaling to serve a larger userbase. The maximum message size is 1 MB and Kafka's messages can be bigger. Kafka can handle the more esoteric and unusual use cases, if that's what you need. One of the major considerations is how these tools are designed to operate. Unfortunately, selecting an instance type and the number of brokers isnt entirely straightforward. Finally, the partition key is typically a meaningful identifier, such as a user ID or timestamp and the sequence number is a unique identifier for each data record. Use cases Although Kafka and Kinesis are highly configurable to meet the scale required of a data streaming environment, these two services offer that configurability in distinctly different ways. This also means that its not ready to go right out of the box. Here, choosing the right instance type for the Kafka cluster and the number of brokers will profoundly impact throughput. Both Kafka and Kinesis require custom monitoring and management of the actual producer processes, whereas Flume processes and the subsequent metrics can be gathered automatically with tools like Cloudera Manager. Further, as a cloud-native solution, Kinesis is fault-tolerant by default, supports auto-scaling, and integrates seamlessly with AWS dashboards designed to monitor key metrics.
