 Summary: 0-byte log segments on topics with log compaction
 Key: KAFKA-7550
 URL: https://issues.apache.org/jira/browse/KAFKA-7550
 Project: Kafka
  Issue Type: Bug
  Components: log
Affects Versions: 1.0.0
Reporter: Jakub Korab


In production, I am seeing some old log segments that are 0-bytes in length. 
There are no associated .index or .timeindex files.  These topics have log 
compaction turned on.

The segments are not creating any issues.

[jira] [Created] (KAFKA-2996) Introduction around queue-like consumer group behaviour is misleading

 Summary: Introduction around queue-like consumer group behaviour 
is misleading
 Key: KAFKA-2996
 URL: https://issues.apache.org/jira/browse/KAFKA-2996
 Project: Kafka
  Issue Type: Improvement
  Components: website
Affects Versions: 0.9.0.0
Reporter: Jakub Korab
Priority: Minor


The documentation reads "If all the consumer instances have the same consumer 
group, then this works just like a traditional queue balancing load over the 
consumers. "

This is then followed up two paragraphs later by explaining how multiple 
consumers on the same partition work like a queue with exclusive consumers, and 
that partitioning is required for parallelism. This section needs some 
refactoring to make it read better - as it stand it's confusing/misleading.
