----------------------------------------
Summary: Too many SharePollEvents created
Key: KAFKA-20309
URL: https://issues.apache.org/jira/browse/KAFKA-20309
Project: Kafka
Issue Type: Bug
Affects Versions: 4.2.0
Reporter: Andrew Schofield
Assignee: Andrew Schofield
SharePollEvent is used in a share consumer to signal to the background thread
that the application thread is polling. The mechanism for governing when to
make a new event is too loose which can result in too many events being
created. Generally, there is only a single event outstanding, but sometimes a
higher number are enqueued unnecessarily.
The AsyncKafkaConsumer introduced a mechanism to control the number of events
and something similar is appropriate in the share consumer also.
