[jira] [Created] (PLC4X-255) Kafka - Source Task doesn't block within poll()

Ben Hutcheson created PLC4X-255:
-----------------------------------

             Summary: Kafka - Source Task doesn't block within poll()
                 Key: PLC4X-255
                 URL: https://issues.apache.org/jira/browse/PLC4X-255
             Project: Apache PLC4X
          Issue Type: Bug
          Components: Integration-Kafka-Connect
    Affects Versions: 0.8.0
            Reporter: Ben Hutcheson


The Kafka source connector causes high CPU usage when running.

Looking at the Kafka SourceTask api, the poll function should block if no data is available and return occasionally. At the moment it returns straight away.

I'm assuming this is causing the poll task to be continuously called resulting in high CPU usage.
