Understanding Apache Pulsar Functions

Apache Pulsar functions can process simple tasks, such as word counting. Handling computations natively within Pulsar can preserve operational simplicity by not requiring additional technology for processing.

However, Pulsar functions don't remove the need for separate technologies for more complex processes. For complex tasks you'll likely want to use Apache Heron, Apache Storm, or Apache Flink.
