I also issued a partition reassignment request on kafka Currently, version 0.9 and earlier do not support compression, and version 0.10 and later do not support gzip compression. This configuration is a balance between production throughput and data reliability (messages may be lost if the leader is dead but has not been replicated yet). A single partition can only be consumed by a single consumer process in the same consumer group. It is important to select an appropriate number of partitions to fully play the performance of the CKafka instance.The number of partitions should be determined based on the throughput of production and consumption, ideally through the following formula: Num represents the number of partitions, T the target throughput, PT the maximum production throughput by the producer to a single partition, and CT the maximum consumption throughput by the consumer from a single partition. Logstash establishes a connection to Message Queue for Apache Kafka by using a Message Queue for Apache Kafka endpoint. If just one group is acting on the topic you should just see just one owner listed. Now this happend twice this week, and everytime I restarted logstash kafka input the plugin continued from the latest point losing all the logs. If you aren't seeing the logs in Elasticsearch in the timeline where you expect them, I'd guess the date filter isn't firing correctly.

To stop transmitting data from Citrix Analytics for Security: Go to Settings > Data Sources > Security > DATA EXPORTS. If you run the consumer now, since there is no existing offsets for some_random_group and the reset is earliest, the consumer should consume all the existing messages in a topic and commit the offsets. There is an existing group with the same group id ("logstash") and some consumer with this group id has already consumed the existing messages and commited the offsets (this other consumer might have been the one ran by you previously or some other consumers with the same group id). Could you check your consumer instance owners again? exist. # 0: the producer continues to send the next message or next batch of messages without waiting for acknowledgement of synchronization completion from the Broker.

From the producer's point of view, writes to different partitions are completely in parallel; from the consumer's point of view, the number of concurrencies depends entirely on the number of partitions (if there are more consumers than partitions, there will definitely be idle consumers).
