-----------------------------
Summary: consumerCount vs consumer
Key: CAMEL-13215
URL: https://issues.apache.org/jira/browse/CAMEL-13215
Project: Camel
Issue Type: Bug
Components: camel-kafka
Affects Versions: 2.23.1
Reporter: Pablo
Hi guys,
Currently we are configuring camel-kafka component, but we don't understand at
all the consumer properties related to concurrency.
According to the configuration:
consumersCount: The number of consumers that connect to kafka server
(default 1)
consumerStreams: Number of concurrent consumers on the consumer (default 10)
But... Having a look to the source code, the consumerStreams is the number of
threads the executor is configured.
And a task is submitted to the executor for each kafka consumer, which is the
consumerCount.
So... I don't see what you get if you configure different values in
consumerCount and consumerStreams with the current implementation.
Basically I expected that if define consumerCount=1 and consumerStreams=10,
which is the default. I would get 10 threads consuming from that Kafka
consumer. But I end up having a pool of 10 threads with only a worker which is
a single thread consumer.
Talking with Andrea Cosentino, seems that this maybe it's a problem in the
documentation.
