----------------------------------
Summary: Producer's BufferPool may block the producer from closing.
Key: KAFKA-9449
URL: https://issues.apache.org/jira/browse/KAFKA-9449
Project: Kafka
Issue Type: Bug
Reporter: Brian Byrne
Assignee: Brian Byrne
The producer's BufferPool may block allocations if its memory limit has hit
capacity. If the producer is closed, it's possible for the allocation waiters
to wait for max.block.ms if progress cannot be made, even when force-closed
(immediate), which can cause indefinite blocking if max.block.ms is
particularly high.
The BufferPool should be made close-able, which should immediate wake up any
waiters that are pending allocations and throw a "producer is closing"
exception.
