[GitHub] hate13 opened a new pull request #6623: Fetch offsets optimize

hate13 opened a new pull request #6623: Fetch offsets optimize
URL: https://github.com/apache/incubator-druid/pull/6623
 
 
   Recently we encountered a problem. When there are too many partitions in kafka topic, loading end offsets of all the partitions is very slow. In this process, the report thread may hold the consumer lock for a long time, which cause the schedule thread task to hang, and no new task could be created.
   
   To solve this, We  replaced `foreach + consumer#position` with `consumer#endOffsets`.
